Chalk those up to embroidery practice, remember to include seam allowances next time, and go get yourself some fray-stopper or pinking shears. Actually, I will look tonight, and it might be dried up, but I had some stuff that is supposed to keep ribbons from fraying that might work.
You should see the backs of these. You'd swear I haven't embroidered anything in over a decade . . . cause I haven't. ;) Halfway through the head I was thinking about scrapping that piece alone and starting over, if only because I messed up a bit and I worry about some threads coming loose. I just hate the idea of scrapping this. It's not a ton of work, probably five or six hours, but I'd hate to throw it away. That said, if I do have to toss it, I got quite a few scrap pieces to try and make some competent flowers and birds with.
