Frarose - what position would you like to quilt in? I use hand-held frames rather than a floor frame, generally an 11" x 17" Q-snap, and I quilt on the sofa or in bed due to disability. I use rocking stitch rather than stab stitch and can't quilt in all directions, so quite apart from the back position I'd never get on with one of those floor frames.
Other hand-quilting tips: I discovered big eye size 11 between needles a while back and absolutely adore them, and I use an Aunt Becky on my under-finger to stop it from getting pricked.
