Thanks! On your instructions, in step 3 you created the end pieces for the bag and marked them for the zipper and for sewing onto the body later. Then in step 10, you use the pocket piece to add the zipper and attach it to one of the end pieces. By the end of step 10, the pocket is attached to the end piece and in step 11, you put it all together. Cherie can help you more if you write to her in the comments section (this is the projects section). Good luck! I love my bag and am happy with how it turned out!
