Judy, sorry to hear that your surgery is slowing you down. It does not sound like fun!
As for the wedding ring and Dresden plate rows, that is my quilt and I clearly said NO STRESSING on my quilt. Grab some black, white, grey or any combination there of and go for it! Log cabins will work just dandy. I have never made anything log cabin so it will be a new, fresh additon to thing around here.
