I have three sergers and I love to sew with them. I keep different color thread on each one. I took a class at the local Sew & Vac Center and learned how to thread the sergers easier. I bought a Singer first, then bought a Janome when my mother bought one and it was more user friendly(I thought) than my Singer. Turns out it was just the operator. Now, I have three to use because after my Father passed away, I moved in with my Mother. I have made the quilts I made for Christmas with the sergers. I was worried about the stitching coming out on the regular machies. But, I think I might go back to my regular Singers to do some more quilts. Sergers are not necessary, but very handy to have around, in my opinion.
