I quilt with my embroidery machine all the time. You can buy the quilting designs from a number of different companies...one good one is Embroidery Library. I use my 150x150 hoop mostly. It's considered a quilting hoop and it has 2 "inner rings"..one for light weight and one for heavy weight. When quilting the "sandwich" I use the heavy weight "inner ring". I have a Husqvarna Viking SE and it works really well this way.
Good Luck, Drue
