What are you most proud of? Doing an entire project on my serger What advice would you give someone starting this project? I accidentally cut off the top of my zipper instead of the bottom while trimming it down. But, since Amy suggests a much larger zipper than you need I was able to snip the bottom off and put back on the zipper head without taking anything apart. I also wanted my bag to lay a little flatter so after I boxed the corners I made two connecting serge lines longways on the bag to create "seams" on the outside of the bag bottom.
