I was just about to post the same thing! I've made a few using various directions and 7/8 ribbon - and just make them 2-3 inches. Those turn out ok (sometimes). It's the ones using 3/8 or 5/8 that just don't do right. I use a small Sally's clip to tie it. I did find these instructions on "baby bows" - have you seen them?

After several days of trying, I finally made one yesterday that looks halfway right. But, at least I know it's possible. The loops always end up falling together.
Good luck - I can't wait to see what everyone else says!
