I used rubberbands this time. I found a place on the internet that sold the inch barrettes (about 150 for 12 dollars) but I hadn't gotten them yet and I really wanted to go ahead and try to make the bow. I like barrettes usually but I do have to say I kind of like having the rubberbands for the pigtails. Its really easy you just take ribbon and wrap in around a dowel or knitting needle or something(I think it needs to be wooden though) and stick it in the oven for a bit and when it comes out its all curly. Wait I could probably send you to a website that could explain it better. This is the one I used hope it helps...
