How did ordinary farmers in ancient times make their clothing?

How common was it for them to have a spinning wheel?

Big wheels like these were introduced to Europe in the late Middle Ages

Spinning wheels came to Europe between 1280 and 1350, which is very close to the end of the Middle Ages, which is very rare. These were essentially huge wheels, which were mechanized spindles. Flying wheels (often still without pedals) appeared a few centuries later. Pedals were not even introduced until later.

In contrast to the popular image, people in the Middle Ages also liked to dye their clothes to protect them from damage, and some dyes were very expensive (e.g., indigo) and some were very inexpensive, such as onion skins

The most common fiber in medieval Europe was wool, followed by linen. Sheep were sheared in the spring, usually after a bath to clean the wool. Wool had to be processed over a long period of time, sorted by quality, removed by hand for waste, washed, and then carded, and combed if necessary. It takes months just to process the wool. Once all the wool has been processed, women and children spin the yarn on drop spindles or support spindles (different types of spindles are used for different fibers, producing different types of yarn), and then usually the men weave the cloth (large looms require a lot of strength).

The cloth was then filled with hot water and sticks to make the wool bloom, feel slightly upwards, become softer and warmer, and dyed: cheap dyes could be obtained from plants used every day, such as onion skins, dandelion roots, spinach, and a variety of berries; the dyes helped to protect the cloth from vermin, and were therefore widely used. During the drying process, one would stretch the cloth, then cut and sew it, and finally embellish it with embroidery, which also served as a reinforcement.

Clothes are colorful according to simple shapes and are often wide, which makes them easier to repair and fit

It takes the best part of the year to make a dress, and the sheep have to finish one. As a result, people don't skimp on decorating them with embroidery and ornamentation. Some reinforce key parts of the dress (such as the neck or cuffs), and some can be used to hide stains or tears. Clothes are also usually roomy, which makes them adaptable to weight gain and easier to repair (maybe even cutting out damaged parts and sewing up the breaks). Usually, a new dress is Sunday's best, used for special occasions. When it's worn, it becomes an everyday dress, and then it becomes a rag used for cleaning.
