I do as everyone suggests but if i still think it looks bad i add a matching piece of material to the back when finished & i zig zag around the outside of the whole thing!!Carolyn
I saw a tutorial on one site and it showed using fabric on the back before the final stitching.
Like jofrog, I simply match the thread on back so design is reversible *
I've done some corner ones, that were all thread, and just matched the bobbin thread so it is reversible.
I found some instructions on www.adorableapplique.com that shows how to do this. I have seen some of the fronts done in felt. Are they suppose to be felt or can they be done in fabric.
I use the fabric on the back. There should be a thread change for this and use colored bobbin thread.
Depending on the design used, I use a piece of fabric on the back side of mine..
