Leather can be used as a simple little object

Gloves, keychains, mouse pads, insoles are all fine, and even dolls' clothes can be used.

Leather is made from animal skins that undergo a very complex physical and chemical process. The difference in animal skins and the change in processing methods have led to a wide variety of leathers.

Traditionally, the tanning process is divided into three stages: preparation, tanning and finishing.

1. In the preparation stage, its main purpose is to remove all useless things on the animal skin, such as hair, fat, various glands and soluble proteins in the skin, and to treat the collagen fibers of the animal skin, that is, the main body of the leather, so as to facilitate the subsequent processing and improve the quality of the leather. The main processes at this stage are: water immersion, meat removal, hair removal, liming impregnation, degreasing, softening, and pickling;

2. In the tanning stage, its main purpose is to change the collagen fibers of animal skin in structure through chemical methods, so that it can change from leather to leather. At the same time, it also determines the quality and performance of the resulting leather. The main processes at this stage are: pre-tanning, main tanning and re-tanning;

3. In the finishing stage, its main purpose is to enrich some special sensory properties of leather, such as thickness, softness, color, surface condition and waterproofness. The main processes at this stage are: layering, shaving, neutralization, dyeing, fattening, drying, softening, flattening, grinding, finishing, embossing, etc.

Handmade leather with vegetable tanned leather, vegetable tanned oil wax, oil skin, crazy horse leather are all available. Chrome tanned leather can actually be used, but it is relatively less popular than vegetable tanned leather.

Vegetable tanned leather is also known as leather carved leather, tree paste (cake) leather, oak leather, belt leather. The color is undyed natural. Vegetable tanned leather has small elasticity, water absorption is easy to become soft, plasticity is easy to shape, and the color ranges from light flesh pink to light brown, which is most suitable for leather carving handicrafts.

Leather made of vegetable tanning material is also commonly known as tree paste skin, and some people write it as tree cake skin. The characteristics of vegetable tanned leather: the leather after tanning and fatting is soft and the leather fiber tissue is compact, the elongation is small, the formability is good, the board surface is plump and elastic, no greasy feeling, the grain and suede of the leather are shiny, and the water absorption is easy to become soft.

Leather that has been tanned with vegetable tanning agents (tannins extracted from plants) or with chemicals such as metallic chromium and synthetic tanning agents is called leather, and the leather that has been dyed, oiled and dried can maintain its quality and flexibility with moderate care. Among them, the leather tanned by vegetable tanning agent (tannins solution) is easy to shape due to its strong water absorption and high plasticity, which is very suitable for carving and leather molding.

It's not okay, it's very good.

Doing fun, you can buy leather and sew it by hand with a sewing needle + cotton thread.

The advantage is that the cost is low, and the disadvantage is that it is very tiring.

If you want to be professional, you can buy professional tools and use professional sewing needles + wax threads.

The advantage is that it looks good to make, and the disadvantage is that the cost is high.

If you feel too tired to sew by hand, use a sewing machine. Generally, electric or old-fashioned household sewing machines can be wagons, but old-fashioned ones are easier to use.

The advantage is that it looks good and the cost is slightly lower, but the disadvantage is that it is not easy to grasp the raw hands, and you need to practice on broken skin first.

Skins and tools can be purchased at the local leather market or online.

I remembered that I had a similar problem before.,Turn it out and post it for your reference.。。。

If you don't pay attention to it, buy some thick cowhide, directly use an ordinary large needle, and wear a few more money to sew. But when I sew it, I guess my finger will be useless, because it is too difficult to thread the needle.

If you pay attention to it and want to have a style, it is more complicated. Like round-headed needles (the stitches do not pierce the hands), special sutures (nylon, very thick, strong), and diamond chops (punch holes before going online to facilitate sewing), these are must-haves. There are also some things about edging, which are tools and materials that make the edging not look frizzy.

**There is a store selling kits, novices can prepare a set.

If you want to have a pattern on the leather or your own name, letters, etc., you have to have a special metal stamp, which can be hammered out on the leather with a hammer. This one is quite expensive, and I am not willing to buy it.

The sewing method of leather is generally double-needle sewing, and the stitches are beautiful and neat. There is also a knot of thread, which is also different from sewing clothes. I can't say a word or two, someone has specially published a book sewn from leather. You can find some of the "leather sewn" **.

Cowhide, if you want to buy it in the local leather market, you can go to the ** to learn first. Materials and leathers, I generally buy on the drifting impression of **, one is that the things are complete, and the other is that each thickness of cowhide, there will be corresponding product suggestions suitable for doing. The owner also has a special learning forum, even if you don't buy it, it's not bad to see it.

However, if you are only interested in it, it is not recommended to buy it, the cost is too high, and the cost of buying skins and tools is much higher than if you buy one. I remember that I spent more than 300 on tools and more than 500 on skins, and the result was to make a mobile phone bag.

Can't you work by hand, just ask the tailor to make one for you with your design idea. I think it's okay to be handmade!

A lot of them are handmade, see if there are any flaws in the stitches, you get what you pay for, I wish you the right bag.

To put it simply, leather is made from animal skins that undergo a very complex physical (mechanical) and chemical process.

Traditionally, the tanning process is divided into three stages, preparation, tanning and finishing.

In the preparation stage, the main purpose of the package is to remove all useless things on the animal skin, such as hair, fat, various glands and soluble proteins in the skin, and to treat the collagen fibers of the animal skin (that is, the main body of the leather) to facilitate the subsequent processing and improve the quality of the leather.

In the tanning stage, including pre-tanning, main tanning and re-tanning and separation, shaving, neutralization, dyeing, fatting and other processes, its main purpose is to make the collagen fibers of animal skin change in structure through chemical methods, so that it changes from leather to leather. At the same time, it also determines the quality and performance of the resulting leather.

In the finishing stage, including drying, softening, flattening, grinding, finishing, embossing and other processes. Its main purpose is to endow leather with special organoleptic properties, such as physical and chemical properties such as thickness, softness, color, surface condition and water resistance.
