That's a really good question! I'm still learning FMQ and don't feel I'm anywhere near good enough to tackle a whole quilt yet. So far I've done some place mats and table runners.
I do a lot of SITD and straight line walking foot quilting. I also have the Husqvarna Viking Topaz 20 and use the embroidery module to quilt my quilts. I usually use single run designs from Embroidery Library, although I have recently purchased a few double run ones as well.
