I saw one of these in an expensive little boutique. I have heard of them, but had never seen one up close before. A mantle quilt is a row of quilt blocks that hang over your fireplace mantle or shelf; choose any quilt block you like that doesn't have to be set diagonally. Nine patch, log cabin, rail fence, attic window would all work fine with their straight side blocks. Maybe red and green for Christmas. Let your imagination go!
