There is an older thread on PatternReview.com about the Summer KwikSew patterns. I must have missed it but someone bumped it up recently. I love these backpacks and I'll have to plan out a couple for my kids. I don't do much crafty type sewing but every once in a while I get the itch. I've really had the itch since I saw the sponsor link on Cidell's blog. Fabricworm has cute fabrics. I think most of them are quilting cotton type fabric. These might be super cute for the lining.
