I have made many log cabin blocks using my serger. They look so nice from the back I hate to hide them with backing! I sew them all and then square them up and sew the rows together with the serger. Easy to make! Chain piecing each block. My serger has 4 threads so is a nice sturdy seam. I also make socks and hats from polar fleece that are wondeful. Very fast and cozy. Love my serger!
