What to look for when buying leather
It can be pretty overwhelming walking into a leather store and seeing so many different colours, thicknesses and types of leather to choose from. To help make it a little easier for you, I have listed 5 questions below for you to ask yourself next time you're trying to choose which piece of leather to buy:
1. What type of leather is recommended in the tutorial/pattern/project instructions?
There are two main categories of leather that you will use in shoe and accessory making - chrome tanned and vegetable tanned leather. The names obviously refer to the tanning process (the process through which an animal skin is preserved). Leather tanned using chromium salts (hence the name chrome tanned leather) tends to be softer, more supple and more flexible than veg tanned leather, and is available in a wide variety of colours, prints and finishes (some of which you can see in the photo at the top of this post). These characteristics make it very useful for making shoe uppers, bags and other accessories.
Leather tanned using plant matter (known as veg or vegetable tanned leather) tends to be stiffer than its chrome tanned counterpart and is generally a light tan colour. It can be dyed, stamped and carved. It can be used to make stiffer bags and belts, and in shoemaking is suitable for insoles, toe and heel stiffeners and even soling (although this is a special version of veg tanned leather that has been compressed to make it strong enough for soling).
Another option is faux leather, sometimes called pleather. This is a synthetic alternative to leather. It is generally sold on bolts (like fabric) so you can purchase the specific length you need (whereas leather is usually sold per skin or half skin with the actual amounts varying depending on the size of the animal it came from).
2. how strong is the leather?
The strength of a piece of leather, and therefore what items it is suitable to make from it, can vary according to the animal whose skin was used to make the leather. The most commonly used leathers in shoe and accessory making are from cows as they are generally quite strong. Kangaroo skins can also be used in footwear as they are very strong, but they are less readily available. Sheep skins tend to be softer and not as strong so this type of leather is often used for linings. You may also see sheep skins where the wool has been left on - these can be used for sheepskin boots and slippers. Faux leather varies greatly in strength, so you need to feel it, try stretching it, and see how it moves, much as you would if you were selecting a piece of fabric for a sewing project.
3. What thickness of leather is recommended in the pattern?
Just as fabrics come in different weights/thicknesses (for example, cotton drill is a heavier weight fabric than cotton voile), leather too comes in different thicknesses and it is important to know which thickness is appropriate for your project. Obviously, thicker leathers tend to provide more structure to the item you are making whereas thinner leathers tend to drape more. Depending on where you are purchasing your leather, you may find the thickness indicated in millimetres, inches or irons.
4. Does the leather have any markings on it?
When you are shopping for leather, it is worth examining the skin you are considering to see if there are any obvious markings that will interfere with the look of the item you are making. The types of marks you might find are scars from scratches or bites, or in some cases even branding marks. Think about where your pattern pieces might fit on that particular piece of leather, and whether or not you can work around any obvious marks, or perhaps even use them as part of your overall design (having marks on your leather item isn't necessarily a problem, it's just a matter of personal preference). This shouldn't be an issue for faux leather, but it always pays to check the piece you're buying to make sure there are no faults in the fabric.
5. Does the appearance of the leather fit the overall look you are trying to achieve?
Finally, and this may seem pretty obvious, ask yourself if the piece of leather you are considering suits the look and feel of the item you are planning to make. Does the colour, texture and/or pattern on the leather fit the look and feel you are wanting? Remember that any thicknesses or other characteristics suggested in the pattern are only recommendations, and while they are recommended for a reason it is also okay to vary from that slightly if the leather you like or have available is slightly different. There is usually a way to work around the effect a different leather will have on the construction and functionality of the item you're making. Similarly, if you would prefer to use faux leather for your project, just look for a piece that has characteristics as close as possible to the type of leather recommended for the project, as well as having a look and feel that you like.
Hopefully thinking through each of these five questions will help you purchase the perfect piece of leather for your next project. And remember, if you have any questions please just let me know.
