Here is a quick video showing how to change the foot on a serger/overlocker even when it does not line up correctly at first.
I want to show you how to thread your serger. This video is for all models that do not have the new air threading capability. We will take a look at those later. By the way, a serger and overlocker are the same things just different names. A cover stitch machine or combination machine is different. Anyway, I hope you find this helpful. I am going to upload several videos focused on serging feet and techniques.
