So this was mentioned in the notes (and I mentioned it there, too), but I know that sometimes those just don't get read. So here I will mention other natural fabrics.
Alpaca- my all time favorite. It is both warmer and lighter than wool, and if you have allergic reactions to wool, as I do, this is a great substitute. Alpaca socks are so great.
Cotton- the common fabric. Good for shirts, underthings, socks, pants, you name it. Good at wicking moisture and letting skin breathe, but can also be woven into warmer items such as sweaters. Good all around fabric. Can be strong and used for heavy duty clothing as well as delicate clothes.
Linen- the original warm weather fabric. The more it is washed, the softer it gets. Fabulous in the heat. Use it for bed sheets in the summer and you will never be hot in bed again. It can be used to make shirts, pants, shorts, and underthings.
Silk- great for warm and cool weather. Cool in the heat, warm in the cold, and beautiful no matter what. Can be made as a washable fabric, but usually hand wash or dry clean. Will wear like iron. If you treat it right, you can have silk for 20 years or more. Gloves, socks, underthings, shirts, pants, dresses, jackets, you name it.
Hemp- less well known but a great fabric. Resists mold like you would not believe! Used to make sails for sailing ships, as well as ropes during the age of sail. It was stronger than cotton when wet and would last longer due to the no molding thing. Less water intensive to grow than cotton, with many of the same properties of both linen and cotton. Can be used to make bed sheets, bath towels, shirts, underthings, pants, socks, pretty much anything.
Cashmere- Super luxurious! It is the shed hair of the Cashmere and pashmina goats. Usually made into sweaters, scarves, hats, gloves , and shawls. Super warm and soft. Hand wash or dry clean.
Angora- Also super luxurious. The shed fur of the angora rabbit. Can be used to make sweaters, hats, gloves, shawls, socks, and shawls. Warm, soft, and fluffy.
Mohair- The fur/hair from angora or mohair goats. Used to make sweaters, socks, gloves, hats, scarves, and shawls. Soft and warm.
There are also natural blends. These include (but are not limited to, and are not a complete list): cotton/wool, cotton/linen, cotton/silk, linen/silk, wool/silk, alpaca/wool, cashmere/wool, mohair/wool, etc.
Other natural fibers can include camel, yak, and other animal hair that is shed or clipped and then spun into yarn. Some are more available in certain areas of the world than others. I did not include bamboo due to the massive amount of chemical processing that it takes to extract the fibers. I also did not include lotus silk, byssus silk (sea silk), or any other experimental animal silk (such as the golden orb weaver spider silk) that has been made/created.
Natural fibers cost more to harvest, process, spin, and weave. They can be more difficult to color evenly, because like any natural material they have flaws and variations. This makes them more expensive to work with, which makes the clothing more expensive to produce and sell. But the items produced will last longer (theoretically), will feel better against the skin, and will be better for you in the long run for both you and the planet than clothing yourself in plastic. Microplastics will rub off on your skin, washing away in the washing machines and getting into the water supply. As the fabrics break down, they will become not only rougher against the skin, but also more difficult to mend and patch, limiting their wear life. But because they are plastics, they won't decompose and break down, continuing to pollute the environment unless they can be recycled.
Natural fabrics, in comparison, will become softer over time. They can be repaired more easily as they get holes or tears because the fabric will not have pieces break off like plastic will. It can be easily recycled, and will eventually decompose (which is why archaeologists rarely find clothing and textiles at dig sites), causing little to no damage to the environment. Rarely will a person be allergic to a natural fabric (WOOL! Argh!!!), and when they are, there is usually a protein, emollient, or fabric composition which can be a factor and can (usually) be mitigated, unlike with a synthetic fiber.
Don't get me wrong, synthetic fibers have their place and they have become very useful for certain things. But, we live in a time of fast fashion and high consumerism fueled by synthetic fabrics and exploited labor. Being conscientious of what your clothing is made of, what natural fabrics can do, how long they can last, and why and when you should wear them is a good way to start cutting down on waste while helping your body feel better. And you may find that by limiting the amount of synthetic materials you put on or near your body, that certain things might start to clear up (acne, rashes, etc.).
I know there is much more about fashion and fabrics out there, and I am 100% certain that there is someone out there MUCH more knowledgeable than me. But this is just some information I had and info dumped.
