I don't use my serger for quilting, but I use it all the time in garment sewing and home dec sewing. I can't imagine sewing knit fabrics without a serger - it makes using them so easy. I also do rolled hems all the time on everything from napkins to flannel receiving blankets - professional and decorative. One of my standard presents for wedding showers is a few sets of cloth napkins - some plain ones and some seasonal ones too. I also have made crib sheets for my twin granddaughters, applying the elastic with a specialized serger foot. Pretty nice to be able to make a crib sheet in 15 minutes! When my children were little, I made dozens of pants, tshirts, and sweatshirts for them with the serger, just putting together an assembly line for efficiency.
Can you tell I really like my serger? I used up an old White after 20 years and bought a new one about 3 years ago.
