I had a tiny bit of an old quilt topo that I got in a yard sale. To make a side table topper I put some real thin muslin on the back and then zig zagged, almost satin stitched in the ditch all over the sewing lines. Had to add binding but still around in my daughter's house. It was "her" colors!! She has to wash it often because of allergies.
Love that pattern, never saw the blocks made that way.
