Flax is 100% linen, made from - you guessed it - the flax plant! Garments made in Flax will have excellent drape and breathability, fine attributes for a warm weather yarn. You'll definitely want to machine wash and dry this yarn - because you can, and because Flax also blooms and softens as you do! This is also a most excellent yarn for home decor and accessories, especially bags. Linen is very strong (even stronger when wet!), so this is a perfect yarn for a market bag or any project that will have a lot of stress put on it.
