That's so funny b/c I had almost that exact thought today myself! I think that is a great idea! I was thinking along the lines of a tip section so each tip could have it's own thread!
My tip: When mailing only a block or two, wrap them around an empty paper towel roll so there will be no set in fold marks. I even use wrapping paper tubes to wrap my quilt tops on-even if there is still wrapping on them sometimes!
