Ever Tried This on Your Serger? This Differential Feed Feature Will Amaze You
Differential feed is a serger feature that adjusts the speed of the feed dogs to control how the fabric is fed through the machine. This can be used for a variety of purposes, such as preventing wavy seams on knit fabrics, creating gathers, and adding a lettuce hem. To use differential feed, find the knob or lever on your serger and adjust it according to the desired effect.
