What I Learned
This has taken some turns I wish it hadn't, and I'd rather move on than keep trying to salvage it, as the work involved for a far less than desired outcome is not worth it. But that said, I never make artistic mistakes, merely prove that some methods don't work, or need tweaking. Also learned some stuff I hadn't tried and really like now.
I've already started on a new mosaic on Wedi board, but I'll post those pics of that in a thread in the Making Work board so as not to hog the member gallery display at the bottom of the main forums page.
