If you want to give it a try before you purchase one, you can try these instructions http://www.girlythingsbows.com/loopy_bows.html
. Then just add pieces of ribbon, ric rac, tulle in between the loopy layers. Cut the extras in little pieces and stitch them in. You can also cut some of the loops to add more funky pieces as desired. Your ribbon can be different widths too.
Also, I have found that if you don't put a stitch through the center of each loop they are a little slippery and can pull out.
