This does not make for a pretty, modern, clean edge at all. Behold...the Frankenstein of cross stitch!
I set this monstrosity aside and did not deliver in time for Christmas. I just couldn't stomach what my lovely cross-stitch had become (visualize a dramatic crafter with her had placed dramatically on her forehead here).
I made a strip of fabric and wrapped it around the canvas, sort of like a quilt binding. In the end, I rather like how it turned out!
