I don't know what it is exactly about these little woven squares, but I cannot stop making them! These are all made with the Weavette 6 in. loom. I'd post a link to their website, but I have tried emailing them to find out if they are still making looms and have never received a reply. My advice, if you want to get addicted to these little squares, is to find a Weave-It loom on eBay. I've had some luck purchasing several in different sizes on eBay over the past year.
