The fabric around the blocks remind me of a men's tie. (The recipient is a young man.)
For the sashing, I'll be using men's shirting. I cut these strips from thrift store shirts.
As I sew a piece of shirt to a block, I'm trimming the excess as I go...
and sewing them together end to end. This will be my border.
Today should be a bit quieter around here - hopefully no jack hammers or flying tiles or dust. I believe the plan for today is to lay new tile on the floor.
