Have you tried the Little Bits tissue paper-pieced patterns by Cindi Edgerton? My 7 yo GGD just gave me 2 for Christmas... storm at sea (finishes as 52.5-inches by 52.5-inches wall quilt) and a feathered star that finishes at 35-inch square (perfect for the center of a wall hanging or bedspread). In the early 90s I made up several storm at sea blocks (my own pp) for some sweatshirts. Pattern wasn't any more difficult than any other pp pattern so I'm looking forward to making these.
