I've had good luck with the water soluble stabilizer which is sold with the interfacings at JAF. I use it for machine embroidery on terry cloth towels. I've found it works great for FMQ when I want an accurate, consistent design. I draw the motif on scratch paper, then lay the stabilizer over it and trace with a pen or sharpie. I adhere it with a tiny bit of adhesive spray and stitch away. Most of the stabilizer just tears away, and the rest can be spritzed with water to dissolve.
