Aaagh it was very close between Cozy Craft Workshop and DIY Delight, but I ended up picking DIY Delight. Love it! It's just so cute and artsy, with lots of bright colors and knitted decor. I liked Cozy Craft Workshop, but it didn't have a lot of bright colors and seemed more serious.
Edit: I have nothing against Granny Chic, I just didn't like it as much. It doesn't have any knitting tools, very little knitted decor, etc. etc.... it fit the theme of the pack, but I didn't feel like I would use many of the items in that style.
