I have owned a serger for longer than I care to admit & absolutely would not like to live without one. I started with a pretty basic one & have upgraded over the years. I now own a Babylock with air threading & that means it almost threads itself. If you have had bad experiences with threading a serger, than a Babylock with air threading is a gift from heaven. Even with using tie on methods etc., air threading is an absolute joy to use, IMHO!
