Is there anything worse than trying to re-thread your serger? I don’t think so. I have a Husqvarna machine, that is really great. I tried to tie off the thread to change colours, but one got snagged and I had to start from scratch. There is a YouTube video on how to re-thread your machine, that I watched over and over. I finally took a screen shot and FINALLY got it to work. Sheesh!
