They had an article on making hawaiian quilts in an early issue of craft magazine, but I think you'll have to get your hands on a print copy to check it out. Most of the hawaiian quilts I've seen are two colors and have a botanical design.
I wish they weren't so expensive, but they are handmade. It seems like it would be fun to create the design. Maybe I can make my own some day...
