My second solution was to purchase white linen fabric, cut it to size, and glue it to the inside of the shade. I used Elmer's spray glue because anything else (like regular glue) would've looked uneven under the fabric because you could see the lines of the glue.
I tried using hot glue on the ribbon first, but again, you could see the lines of the glue. So I used fabric glue but used a paint brush to apply it to the back of the ribbon. Now, you can't even tell that I 'doctored' the shade...it just looks like it came that way! Ba-buh seashells and anchors!
