ok, this is the latest block. I took a long time working out which fabrics to use, and took sneaky peeks at what others had chosen to do with theirs, before getting down to it. I think I am reasonably satisfied with my result. I will need to trim it a little. It sis supposed to end up 12 1/2" square, but when trimmed will be 12 1/2" by 12 3/8". I expect it will do!
