I love my serger!
I love my serger! And I don't really mind (too much) when I have to re-thread it. If I am just changing thread colors, I but the old thread near the spool and tie the new thread on to the old piece and run the machine until the new color thread is all the way through the serger. BTW: a square knot works best - you know - right over left and left over right. You learned it in Girl Scouts.
