Love my serger...not sure what I did without one. I do a lot of garment sewing and would not make a garment now without one....
There are also books and instructions for many projects for sergers....making your own wired ribbons...so simple and much cheaper than buying it. Scarves, hemming, quilting, all sorts of crafting....just go on line and check it all out. The threading part is only as hard as you make it....and I must admit that occassionally I make it hard...then I slow down and figure out that I missed one little thing and then...WALA!!!!
Enjoy the new toy!
