It was oh so easy to put together. I bought the foam wreath from from Michael's, the butterflies from the dollar store, and I think the yarn came from Walmart.
I used a dab of hot glue to attach the end of the yarn, then just wrapped the yarn around until the wreath was all covered. I snipped the yarn and secured the end with another dab of hot glue.
I added the green butterfly, but I'm not sure if I will keep it, or if I will add some fabric rosettes instead. Because the butterfly has a clip on the back, I can change my mind easily!
