Welcome from Texas. You've come to the right place for answers to any of your quilting questions. I've never done a quilt like that before so don't know what to say to help you but I'm sure someone will come along with answers/suggestions/solutions to your question. I've been working on a quilt for our Calif. King bed but mine will drape over the mattress & have borders beyond that. I'm going to finish the blocks using the Quilt As You Go method so I won't have the entire quilt to quilt all at the same time.
By the way....we love pictures here.
