Importance of Paper Designing in Leatherwork

Designing is an important step that ensures the success of any article.The truth is that the leather material for the production of items are costly and as such, a leather craftsman cannot just experiment with it, thus, paper is used to test the feasibility of a particular design before it comes to life using leather. Detailed merits of paper designing prior to actual three-dimensional production in leather sounds professional and advantageous for many reasons,some of which have been dealt with in this article.

1. It helps us to generate various unique and original designs from which articles can be produced- Designing takes several phases or stages in their development which some designers’ term as idea development. This systematic development ensures that original designs which are not already in existence are created.

2. It helps designers in incorporating client’s preferences into the design of the article- When articles are carefully planned and designed, it gives designers the opportunity to include the taste of customers with respect to colour, shape, form, etc. in the design. This deepens the trust that clients have in the leather craftsman, paving the way for commissioned future projects.

3. It helps designers to visualize the final outlook of the product- Designing of products before they are actually produced help designers to first preview how the product to be produced will look like. Thus, when shown to clients saves designers from unpleasant surprises from clients.

4. It helps us to make corrections before the preparation of templates and the cutting of leather- If designs are first generated before actual production, corrections can be conveniently made before it’s too late. When designs are made and shown to clients before actual production, the changes the client wants the designer to make can be easily carried out.

5. It saves time and resources- All the toils and difficulties that result in the production of articles is mainly due to the failure of leather craftsmen in taking ample time to plan and design the article. However, all the efforts in designing is time worthier. This is largely true because the time and resources that would be wasted if a mistake is committed would be far greater than the time that was spent in designing.

Owing to the enormous advantages of designing products before their actual production, the author of this book is advocating that a product in leatherwork must not be produced if the paper work (design) is not carefully and properly carried out.

Flying Model Rocket Safety Tips

Model rocketry has a very good safety record, but, although they are sold as toys, they still need to be handled with care.

Here are some basic guidelines that you should be aware of if you are thinking of buying a child a model rocket.

Recommended Minimum Age

The recommended minimum age for flying model rocket kits is 10 years old, and it is also recommended that an adult be present for a rocket launch if the child is under 12 years old. However, there are some states with different rules. In California, New Jersey, Rhode Island and North Dakota, there are age restrictions on the purchase of rocket engines and there are some other restrictions on the use of model rockets. More details about these sate specific regulations can be found by following the link at the end of this article.

Treat Rockets with Respect

While model rockets may be classified as toys, they are not something that kids should be playing around with. The biggest danger is not from the rocket propellant itself, that only burns for a few seconds and it is a lot less flammable than model airplane fuel. The biggest danger is from being hit by a stray rocket that could be flying at 200 miles an hour or so. That’s why common sense precautions, like staying alert, standing well back and treating model rockets with respect are so important.

Read the National Association of Rocketry (NAR) safety code

Model Rocketry is self-regulated in the US and the main source of safety guidelines is the National Association of Rocketry (NAR) safety code. This lays down a standard code of conduct for the construction and the flying of model rockets and it is an excellent document for youngsters to read when they get their first model rocket.

Only Use Commercially Available Rocket Engines

One of the biggest causes of accidents in model rocketry is people trying to concoct their own propellant. Stick to commercially manufactured engines and commercially available rocket kits available from reputable manufacturers like Estes, unless you really know what you are doing. You should also only use the engines that are recommended by the manufacturer for any particular rocket.

Do Pre-Flight Checks

Even the best model rocket kits can develop flaws, especially after they have been flown more than once. Always give your rocket a final check over before you launch it. Make sure it is stable on the ground and it won’t fall over when the engine ignites, check for any loose parts, and make sure that the nose cone is not on too tight and the recovery system is not packed in too tightly.

Use an Appropriate Launch Site

Choose a launch site that is in an open area and is away from buildings, highways, power lines, and any low flying aircraft. Also check that there is no dry vegetation near the launch site that could be ignited by the engine. Wide open spaces are best for safety reasons and it will also make recovery much easier as well.

Launch Precautions

At a lunch you need to be aware of what other people are doing as well as following some basic rules yourself. When you are preparing the rocket for launch, make sure that no one else if playing around with the launch controller. Make sure that everyone is clear of the launch area and give a loud and clear countdown before launching.

Are Model Rockets Safe

Model rocketry is and exciting hobby and safe one. Like any hobby of this type, you need to follow common sense rules and not take any risks. In fact, model rocketry is far safer than some other hobbies that kids could take up and it’s educational too.

Tin-Cure and Platinum-Cure Silicones

Silicone rubber is a material of choice for many mold makers and casting artists. The excellent flexibility, superior strength, enhanced resistance and long life work in its favor apart from the versatile usage for almost any application.

Silicone rubber comes as a two-part formula that can be poured, sprayed or brushed on the model/mold. In fact, it is safe and can be used for both mold making and casting as long as it suits your application. Another benefit is that silicone does not stick to anything, so a release agent is mostly not required.

Silicone rubber is often used for general mold making applications as the molds manage to capture fine details and can be made very quickly as well. Most materials – all types of resins, foams, wax and some low-melt metals – can easily be cast in silicone molds. It is also suitable for making soaps and candles, sculpture reproduction, cold casting. Special rubber variants can be used for making food molds, realistic masks, doll reborning, special effects and even life casting.

Types of silicone

Silicone rubber polymers come in two variations – platinum-cured and tin-cured. Both these types are very different from each other and are not even compatible with one another. Let’s find out how:

  • Tin cured silicone rubber uses tin salts (usually 5%) as a catalyst to initiate the cure from liquid state to solid. This is also known as condensation cure. Platinum cured rubber has a platinum catalyst (usually 10%) for curing and is also known as addition cure.
  • Tin cured silicones require moisture for proper curing and excess humidity can accelerate the cure time whereas humidity does not have any effect on the curing of platinum variants at all.
  • Tin cured variants are less expensive and also prove to be easier to use while platinum based ones turn out to be quite expensive.
  • Tin cured silicone molds and casts may tend to shrink a bit at times while the platinum cured counterparts enjoy virtually nil shrinkage.
  • Tin based silicone is tear resistant and even considered biodegradable. Its counterpart is considered very pliable and tough.
  • Platinum cure silicones offer exceptional heat resistance and work better in high temperatures than tin cure ones. The former can even be heat accelerated for faster curing.
  • Platinum cured silicones require very accurate and careful mixing, but this is not the case with tin cure ones.
  • Tin cured silicones are primarily suited for general silicone mold making, prototype applications and prosthetic works. Platinum cured silicones provide good dimensional stability and work well for precision molding, special effects applications, encapsulations and paints. The latter comes in food safe, skin safe and transparent versions also.

So, go ahead and make your silicone mold by all means, but do choose the type of silicone rubber with care.

Types of Modeling: What Type of Model Are You?

Modeling is a business with a large variety of styles and caters to people of all ages and sizes. From the kid next door, to a college girl, or a 50-year old dad, anyone has the ability to become a model; it only depends on the style of modeling you are best suited for. Here we list the various kinds of styles that are provided by the various modeling agencies and help you discover what works for your look.


This is the where the strict requirement and the toughest standards for models are imposed. Usually fashion models taken for consideration are above 165cm, but generally people above 170cm are preferred. A slender figure is also preferred in most cases for this style. There are 4 main categories of fashion modeling namely, Runway, Editorial, Catalog and Fitness.

Runway: A person is required to do a professional catwalk in order to market a particular brand or fashion wear. Confidence and good height are required in this.

Editorial: High-end fashion magazines where a stylish fashion sense is showcased. A model should have good height, distinct looks, and a camera-friendly photogenic appeal.

Catalog: Print ads for various publications to present different types of clothing wears lines and products. Being photogenic and expressing various moods and emotions are important here.

Fitness: This type perhaps has the toughest body requirements and maintaining your body figure is an essential enduring process. The opportunities here are limited as there only certain kinds of sports and lifestyle brands that require the employment of fitness models, and as such, the competition for this modeling type is very high. But if you do get the opportunity, rest assured, your payment will be a hefty amount.


This form has very little requirements other than a marketable look and personality. Anyone with passion for modeling has a good chance at excelling in this field.

Other types are assessed for good acting and role playing, and conversational skills are Television Commercials, Television shows, trade shows, entertainment magazines, event campaigns, and website videos.

Commercial print type of modeling also falls under the commercial category, which include Corporate (E.g. Nurses, Doctors, lawyers), Fitness, Swimwear, Lingerie, Glamour (Modeling with sexual appeal, such as Maxim/Playboy types, only for those above 18 years old.), and Alternative (E.g. Rock, Gothic, Indie looks etcetera).


A specific form where one represent a brand, good or service. The modeling criteria are not very stringent on the model’s looks but rather the focus is on the ability to sell a product or idea, being able to communicate, and having an outgoing vibrant personality. Models are mostly used for an event, conventions or shows to promote their brand to consumers.


It is growing in popularity because of its industry and market relevance. This is an area modeling agencies are increasingly picking up on. People here don’t fit the conventional modeling standards, but have heavier weight and present a fuller bodily appearance.


Freelance models are not bound to any agency and instead functions like a self-agency. They would have to source for their own clients, manage their own schedule, and promote their own works by creating their own portfolio, comp card, website. They may also work for multiple agencies and not be a contractually signed model for any particular agency. This all sounds very taxing on an individual, but upon establishing the right contacts and working out a proper management routine, this form of modeling is one which may gives higher levels of flexibility and greater number of opportunities.

Body parts

This is a modeling style where specific body parts are modeled for. Most commonly the body parts requested for are hair, legs, and hands. This requires the model to maintain the beauty of the specific body part well and lead a healthy hygienic lifestyle. For example, a hand model must take the effort to wash the hands regularly, cut the fingernails properly, go for manicure if necessary, and lead a healthy lifestyle to maintain the natural skin glow. If you think you have a nice shiny and luscious hair, smooth and beautiful leg or hand, you can highlight your interest to a modeling agency.
