I had never used an overlock-serger before. My sewing machine was in the shop. I had to go with the serger. I had a 4 yard length of fabric that needed to be finished on the bottom. There is a 8 inch scalloped edge all the way down. I was able to 1-cut the excess fabric off, 2- finish the scalloped edge and 3-have it done quickly. It took me 45 minutes to do my project. I was thrilled with the ease of this machine! If you can work a sewing maching, you can use this machine! Highly recommend this product!
