Sorry for the lack of info on the backpack. Here's the scoop.
The pattern was ordered from Yarnmarket. It's called Paint Box Colors Backpack by Knit One Crochet Too. The yarn is from JoAnn's. Its called Bellezza Collection Cosetta. It's a wool blend 68% wool, 32% nylon. I am hoping for the same or nearly same effect that I got on the Extra Large Altered Booga Bag I did with the Lion Brands Landscape yarn. The JoAnn's yarn has a metallic thread through it. So it will be interesting to see how this yarn felts.
So far the pattern is wonderful. It's easy to read, very clear and looks like it will work up quickly.
