I don't have a pattern. I just cut two squares about 15" by 14" for the top of the bag, and then two rectangles for the outside pockets about 8" by 14". I do the same for the lining, but when I sew it, I make the seams a bit bigger so the lining fits inside the bag better. I make 6" seams for the bottoms of the bags so they have a large inside bottom. It's hard to explain, but it works. The handles are 21" long.
I love how this bag turned out, but I had sooo much trouble putting the zipper in! LOL I think I will stick to the magnetic snaps from now on unless I can find a really good zipper tut. This is the bag I'm going to be carrying for Spring. :-) It has four outside and four inside pockets. What do you think?
I've done lots of these now. I even sold a couple that I covered with leftover fabric. I got $3.00 each for them, which surprised me since I didn't have a penny into them. Can you believe some people think they can't craft at ALL? Sheesh!
