What are you most proud of? Making use of my serger and learning how to do exposed zippers. What advice would you give someone starting this project? Serging over the zipper coil is difficult. I would rather lift the presser foot and move the needles over the zipper coil and resume serging. Then I would go back and straight stitch over the zipper coil using a sewing machine. The layers of fabric can also shift while serging so I would baste the layers using a sewing machine or the instructor suggested Wonder Tape to secure the layers before serging.
