I am on Serger #2 (unfortunately an older one and not a thread itself one). Serger #1 died from overuse. With Serger #1, I made ALL of my kids clothing, swim suits as well as many craft items.
Now that I spend my time quilting with minimum clothing construction, Serger #2 gets used often when I do construction of bags, pillows and other things made out of pieced parts. I also use it on the wide stitch width with a long stitch length on edges of quilts before binding.
If you do embroidery, you can make embroidered napkins out of any fabric, then use the rolled edge to complete the napkin.
Many more uses!! I would not be without mine. I leave it threaded - all ready to go. If I need to re-thread it - I just do the cut, tie and pull trick! (I do know a lot of gals whose serger is an expensive paper weight however mine is not :lol: )
