I started using the hoop... I hated it. I went to the Q-Snap. really liked it but found it bulky... now I use a Grip-n-Stitch / Clip-n-Stitch.
Like the Q-snap it is adjustable, smaller on the frame. and great for packing. I did not like the Grip part of it, so I used it as a clip. Best in hand frame i have used.
I also have a large floor frame (got second hand(and being a cross stitch horder had to have it) but i have never done a large enough project to use it
I use a floor standing frame for large projects and a table top frame for smaller ones. Ive never mastered a hoop, I always over tighten the screw and my aida goes all skew whiff!
I definitely vote for q-snap frames. No matter how long I leave it in the frame it does not permanently damage the fabric. I used to use scroll frames, but my projects are getting bigger and bigger, and thus, dont fit.
