QuiltsRfun & Amma - get using it! lol!! I don't have the actual Flynn Frame, but the one DH made me is quite similar. My backings are always smooth using it! No puckering, etc, at all! I just made a small wallhanging, just used my machine to fmq it, and sure enough - there were a few puckers, blips, in the backing! I apparently can't do any fmq without using the frame!
