Answer:
Knowing whether yarn is wool or acrylic is very important. Some people are allergic to wool, while other people find woolen garments more comfortable to wear.
Explanation:
Look for a hairy texture. Acrylic yarn may feel rough, but it won't look hairy. Wool yarn may have some longer fibers sticking out of it. Keep in mind that acrylic-wool blends may also have some hairy fibers. Yarn made from other natural fibers may also have a hairy look to it.
Cut two pieces of yarn that are several inches long. Make sure that both pieces of yarn come from the same skein. In this method, you will be "felting" the yarn. If the yarn fuses together easily, it is made from wool. If it does not fuse together easily, it is made from acrylic.
Dampen the long threads. You can do this simply by dipping them in water, or misting them lightly with a spray bottle. You can also lick them.
