I recently was given a Grace quilt frame for hand quilting that looks a lot like the EZ3 frame. It does not have any instructions on attaching the quilt to the wooden rails. I note the EZ3 has metal rails to attach the fabric to. However, this frame is older as it has wooden rails. Can anyone give me information on how the fabric should be attached? I emailed the Grace company asking this question, but so far have not heard. Thank you.
