I cut the bandana into long ovals (more like strips with rounded edges). I found it easiest to fold my template in half, then fold a strip of fabric in half and place it inside the template (as if you are filling a taco).... then I could hold the folded template tight with the fabric inside as I cut. One bandana makes 18 6"x3" ovals.
The bandana had been previously folded, so some of my fabric ovals has creases and wrinkles. I could have ironed them, but instead I just used my large hair straightener. One swipe through the straightener and they were flat!
Next, I gathered the center of each oval and tied them together with thin wire. I tied three ovals together (making six petals), then gathered and tied three more ovals to those (making sure the flower had no large gaps). Six ovals makes a flower with 12 petals.
Since my friend needed just one large flower I tied these three together. I hot glued a circular piece of felt and a clip on to the bottom. Now this flower can clip anywhere!
