There’s a dial on my serger labeled Differential Feed. I don’t entirely know what that means so I never touch it. Irene from Serger Pepper explains differential feed in a post on Craftsy. A short explanation is that this setting controls the difference between how fast the front and back feed dogs pull the fabric. Read her post for a more detailed explanation, including when to use different settings and how to identify and correct problems with your differential feed.
