For very special people and very special projects, I love using silk ribbon. This is a product used by people who love doing silk ribbon embroidery, so if you go looking for it, look by the embroidery floss.
You'll find silk is the most wonderful stuff to work with. It comes in lots of beautiful colors and it bunches and gathers in the loveliest way. Here I simply used a needle to stitch it in and around the die-cut flowers and as the border. (Click on the image to get a better look at what I'm talking about.)
