I've been using a lap frame for a couple of years. I bought it from Jean's Impressions. She's the lady who sells and teaches using the Aunt Becky tool (for the "thimble" underneath the quilt. It's a 14" frame and costs $51. I have quilted up to full size on this.
I just recently bought a Grace Handquilting Frame with stand. I have a queen size quilt to do and didn't want to use Jean's Impressions for so large a quilt. It is a fantastic frame, and costs @$300 new.
I was lucky enough to find one for sale on the quilt board! You might want to keep your eyes open. It saved me a lot of money!
