I made a Noni flower from one of these books, then embellished by making an I-cord stem that wound around a bit on the front of the bag. Also found a free pattern for leaves, felted them, and sewed a few of them to the I-cord. It came out looking pretty cool. You could even make the I-cord long enough to wind around to the back of the bag.
