I feel so happy right now! I have been having this love hate relationship with my serger ever since I bought it last year. The lower looper thread kept breaking and it drove me crazy! Plus it seemed so hard to figure out the correct tension. I've read the manual and re-threading countless times, and still nothing changed. I've been procrastinating on this one dress that I'm making for Sarah because the seam allowances need to be finished. I wanted to use the serger for that but I was dreading it because of the looper and tension problems.
