I am trying to figure out a way to have a more streamline sewing process for multiple outfits. My husband is offering to buy me a serger/cover stitch machine for Christmas. The first pair of bed time story pajamas that I made I zigzagged the raw edges and pressed open. I have 3 more pair cut out. This is probably a silly question but can I use a serger to finish raw edges on the bedtime story pajamas separately and press open? or do you only use a serger to finish 2 raw edges together at once and press to the side? I have several hopscotch tops and nature walk pants cut out for my granddaughter too.
