I have finished a plastic canvas project. I did not cut out the pattern before starting. It is completely finished. I don't know how to cut it out so I can whip stitch around the edge. Can you help
You could most easily finish it as an ornament. I have never heard of anyone using a plastic canvas piece for a pillow as it is not soft, but that does not mean you cannot decide to it!
To finish the edges, carefully cut out the bell. Leave one row of squares around the edge if you want it a bit wider or if it makes you nervous to cut closer. After it is cut, choose one of your yarns and work a whip-stitch all the way around to cover the edge. At this point you can sew it to something else like a pillow, or you can ad a hanging loop to use as an ornament. If you are not happy with the backside, you can cut out a piece of felt and glue it to the back.
