Thanks! I'd forgotten about allowing for quilting ease and thanks for the heads up about the binding. Hmmmm.....
I might make my boarders a bit wider to give some breathing room. I think I will piece the rest of the top and put it on the bed to see how much of a boarder I need. I like the idea of using a larger batting. I was thinking of a larger drop on this quilt. The larger batting would keep my options open.
Now that I have a handle on the math I need to practice my 1/4 in seams.... I keep reminding myself, progress not perfection.
thanks for all the help!
