Why not just sew on a border from a strip of material like you would with a regular quilt top? Because there are no seam allowances on the paper pieces so I would lose most of the pretty little half tumbler edge if I did. As for that color, I pulled out Daddio's fabric stash and went for the brightest color I could find because that's what he always did. He wasn't timid about mixing patterns and colors so I tried to keep it all in the spirit of the designer. I can't wait to finish it and take it for him to see. I bet he remembers this one.
