Thanks everybody! For now I have stacked all my other ready-to-put-together pinwheel block pieces in a corner until I decide what to do with the one block I am having trouble with...perhaps I'll make a "signature block" and kind of "mix it up" with the pieces/scraps I have left. I want it to be a kid-cuddle-quilt anyway, so this is one of those "finished is better than perfect" projects that lends itself to interesting solutions!
