Myrna - look at the post from wudbquilter a few below yours on the same day - the one that shows string quilts made on a 3" roll of adding machine tape. If you use only pink and/or white or pink and white fabric on a roll, then pick a quilt pattern to use the 3" pieced roll, you might have just what your sister wants - (or not - LOL). Just a suggestion!
