A finished hoop hides the raw fabric edge. Three methods, in order of finish quality.
Gathered
Run a long gathering stitch around the excess fabric, pull tight, knot. The quickest method.
Felt-backed
Glue a felt circle onto the back. Hides the gathered fabric and gives a clean wall-side surface.
Laced
Lace the gathered fabric across the back with strong thread, in a star pattern. The most secure — recommended for hoops you intend to keep for decades.
