How to manage a backing that is too small for the hoop or frame
As long as you have a flannel gripper cover or some means to protect your arms and hands while you hook, the pattern does not have to fit the frame perfectly. You can adjust the piece off to the side and pull it tight on the top bottom and one side, to hook away happily as in the picture above. Once, thinking I was finished a project, I trimmed off all the tiny frays, steamed pressed it, zig zagged around the edge leaving 1 ¼” border and cut out the rug before I realized I wasn’t happy with one of the colours on the border. So I slapped it on the one end of my frame and hooked the change easily.
Sewing strips of wool along an edge to extend it enough to put on a gripper frame or in a hoop works nicely but when sewing you should use a zig zag stitch because of the loose holes in the burlap or linen backing. Cotton Monk's Cloth is tighter holed so sewing with a straight stitch will work and rug warp is fairly tight as well.
