I have made several quilts with the serger,it works well as long as you have a pattern with straight line stitching. My favorite is 'bricks', it goes together quickly, and there are no seam intersections - that's important with a serger. I have 4 threads, but if worried about weight, you coud use 3 threads. I like the speed. I am not a fan of denium quilts, but I think a serger would handle the heavy material better that a regular machine.
