Unprepared, raw edges of a needlepoint canvas can catch & snag your thread as you stitch. This can ruin thread, and cost you more time and materials in a project.
By using a simple tape binding, you can avoid the dreaded snaggies.
In this photo, you see the unbound canvas. Photos showing how to bind the canvas follow in the next 3 steps.
Note: This canvas is from Cheryl Schaeffer Designs.
