I have used my serger almost exclusively for the past 8 years to piece. It does add a bit of bulk to the seam but since I was handquilting away from the seam it didn't seem to matter. I did like the fact that I didn't have lots of stray threads. I have begun using my regular machine for piecing now because my serger is beginning to show serious signs of aging and I would like it to last until the 20 year mark! I don't want to spend the money now to replace it! I don't sew clothing without it though!
