I don't have an EZ3 Grace frame, but do have the Z44. My instructions call for at least 4" extra backing rather than 2". I also run a basting stitch on both sides through the sandwich (an inch to 1/2 inch from the edge) as far as I can reach as I go each time I turn. I think this helps prevent slippage. I know this information comes too late for your current quilt. Whether you add more to the backing, use a wider binding, or trim 1/4", it will not matter. It will be a beautiful quilt you can be proud of. Congratulations on completing a hand quilted quilt. It takes patience and perseverance. I am sorry you are having problems with the EZ3. I love my Z44. I am just finishing up my third quilt on it with two more waiting their turn.
