What are you most proud of? I am proud of all things that I handmade. What advice would you give someone starting this project? After doing a few of these, I realized that you don't need to serge the zipper to the bag; you can just sew using a straight stitch from the sewing machine as the zipper is encased between the layers of the outer fabric, fleece, and lining. You can still serge this part if you want, but you can save on thread. I serged the rest of the bag. I still having some trouble centering the tab when sewing up the sides. I must be mismarking the center or fabric shifts as I am sewing.
