I needed some 100% wool yarn for a weaving project I was working on, and could not find it anywhere in the major stores. I then turned to this small store that, voila, did indeed stock my 100% wool yarn. If there is a hard to find yarn you need, feel free to call up Yarn Heaven. They also offer classes for those who are beginners and interested in learning how to knit. Lots of selection for a small store.
