Here’s one for the alpha and omega that I art bombed. I got it from one of the Priscilla books that can be downloaded from the Library of Congress at the link at the top of the page.
Here’s my stitched version. I messed up the count a bit. I wouldn’t mind doing this again, with a slightly corrected pattern. I actually graphed it all out so that the two letters are perfectly interwoven. I also made the top of the Alpha slope a little more, to look a bit less pagoda-like. I’ll rework it some rainy day, but not soon.
