Well here is my report on my practice piece. My serger is new and I haven't taken the class. I might have to adjust something, but the pressure of the serger knocked my piece out of square. I'm not going to do anything to it, because it isn't a real quilt. It was fun to just skim the edge and make everything even. If there are some hints regarding tension, type of stitch, etc. I will await them. I am using the 4 threads and have a pretty wide stitch.
