Quiltykitty ~ I, too, have a Fab-U-motion (with opitional stitch regulator mechanism) that I bought this year to use with my Pfaff. Hate to say it, but it has been a huge disappointment for me. I guess I'm just not coordinatd enough to get the hang of that small window space that you have to work in. I tried all summer, practicing on scrap fabric and trying to master it but no such luck. I'm planning to sell it. Anyone interested? I think I'll post an ad on the quiltboard ~ Nita
