I put these on lined double pronged alligator clips. They're time consuming. I'm pretty diligent with the details. It's all made with ribbon. I'm just guesstimating that it took about 30 mins each, I just know it took me awhile when I made my first one. I loves these even though they're a pain to make! All made with 3/8 inch grosgrain ribbon. I'm trying to find the website I found this on, but am having no luck. I tweeked it to my liking.
