Satin Stretch Loops are 1/2" stretch bands with a pre-tied bow. Loops stretch to give you flexibility and make gift wrapping easy. Perfect for jewelry boxes, candy boxes, and small gift packages. To determine which size stretch loop you need, wrap a string or narrow ribbon around the item in the path you want the loop to take. Then measure the string on a flat ruler to find the total inches of the path. Select a loop 2 to 3 inches smaller, to allow for stretch.
