Like all the other answers, I love my Babylock with the air threading. I use mine for making slipcovers, pillows, curtains, hemming prom dresses for Cinderella's closet every year, cover-stitch hemming my vertically challenged DD's sleeves and exercise-type pants. And yes, I have even made some simple project Linus quilts on it. Just this morning, on Fons and Porter, they demonstrated making a Drunkard's Path quilt block using a serger for those curves. It looked so easy that it's now on my quilt bucket list.
