Love all the folks on here asserting that there’s no market for craft supplies. The market for yarn specifically is actually so large that it supports a huge number of local yarn shops in addition to multiple big box chains. Everywhere I travel, I find more than one local yarn shop, somehow thriving in spite of Joann and its ilk charging considerably less for what you might think was a similar product. (In reality, the yarn sold at local yarn shops is much higher quality.)
