I have a Gracie King frame which can be set up as crib, queen or king. The craftsmanship is wonderful and the instructions were excellent. I use a Brother PQ1500S on the frame and quilted a queen size one it with no problem other than as you roll the quilt the rows get narrower. Going to try loading the quilt side to side rather than top to bottom next time. I am considering upgrading to an 18" machine and want to keep my frame because I like it so much.
