This patterns uses 11 different colors of yarn, but just a bit of each one, so it would be great to adapt to your stash yarns. I didn’t use the yarns suggested since I can’t buy them very easily where I live, and I had some cotton yarns I wanted to use up. It’s possible to buy the magazine in the US off of Amazon.com where it was going for $10.95 (http://www.amazon.com/Creative-BAG-MAKING-Magazine-Specia...).
