I used Sweetwater's Pack and Go pattern to make this bag. The pattern was easy, but it was not lined and it had unfinished seams, which I didn't know when I bought it. Well, I added a lining, but the seams were still unfinished. I think I have thought of a way to fix that next time. I am not a fan of unfinished seams. Of course, the zipper is wonky and backwards....it was not going so well in the sewing room last night. Next time, it will be better, I do love the size of it.
