I recently made a log cabin with a serger and it was wonderful the way all the seams were flat and smooth. I did not use small, cut pieces, I used the long strip method. My first one on a serger was a rail fence....again, long strips, then cross-cut. The best use of the serger for a quilt, however, was when I made was one of those 1600" jelly roll races. That went together SO FAST! The trick, IMHO, is to use the serger for big, long pieces that can then be cut to size, not little block or stars, etc,
