A Grace frame is mfd. by the Grace Company and they now also make frames that enable sewing machines with deep throats to machine quilt. Check the Grace Company website for more info. It is wonderful as you can roll the quilt as you finish the rows and no need to baste or pin them as it is all done in one shot. Wonderful!! My husband bought it for me when i started quilting and even if it does take up a bit of space when i am using it, it is great. It does fold up neatly when done quilting. Hope it helps out as it really does save a lot of work.
