I add a single layer of white felt directly behind the stitching to protect the stitches and make the un-stitched holes in the Aida cloth less noticeable. A double layer of white cotton muslin is hand-stitched to the back to help hold the Aida cloth tightly in the hoop and give the back a clean, finished appearance.
Want to stitch this yourself?
