I have a book (it's only about 15 pages) with patterns using 60-degree cuts. It's called Sizzlin' Sixties by Heather Mulder Peterson. All the designs are hexagons based on the 60-degree angles. Quilts and table toppers. I've seen samples in an LQS, which is why I bought the book. I just haven't made any of them yet! The author recommends the Creative Grids 60-degree triangle ruler, which I think is readily available.
