Serger's are a great tool to have if your budget will allow. They are not difficult to learn, it's just like anything else in life, you need to practice using it. I have read on this board, so many posters say that they have a serger,but, it sits in it's box and they have never used it. What a shame! If you make fleece baby blankets, a serger is great!If you make napkins, a rolled hem feature makes hemming a napkin a breeze. You can make reversible quilts with them, check out the Bernina video's on the Quilt Show. If you make garments, most of your sewing can be done on the serger. A serger cuts and seams at the same time. A lot of quilters on this board use their serger to keep the fabric from raveling when they pre-wash their fabrics. Check out Sewing with Nancy website, she just had a 2 part episodes dealing with sergers. Check out You Tube to see serger video's so you can see what a serger does. Enjoy!
