There are 2 pages of corners here on Cute Embroidery if any of them will work for you.
Thank You. I searched my designs and found that I have the pack of corners from cute. That's what happens when we get so many designs.
I have several corners and blank monograms that might work. Not free, but reasonably priced.
Here are the direct links for these categories:
