I toyed with the idea of finishing it anyways and selling it, but decided I didn't want to use up all my white tricot in exchange for a few bucks. So I cut apart what I'd done, in order to save the flat pieces, and picked off the lace edging again - so I can reuse it for the third time.
So now I'm back to square one. This time I'll use the new pattern, but with the original thin cotton again. I hope it works out how I want this time......
