hello,
I love the ribbon roses! I have not made one yet, but I have bookmarked a website that shows a method for making a rose out of paper that I think would work great with ribbon, it is different from the one in this thread. I have tried it with paper and it looks good, so I don't see why it wouldn't work with ribbon. I don't use the "tool" that they use, I just hold it with my fingers
