Frame (Mine was a Goodwill $5 find that I spray painted)
Butterfly Hole Punch (Mine came from Hobby Lobby)
Mat (Optional, mine was cut at Hobby Lobby)
Hot Glue (or any other strong glue)
Get your frame and backing ready. Measure out even spacing and mark with pencil for your butterflies. Punch out, bend the wings and apply hot glue to adhere them to the frame. Super simple and my daughter loves it in her room.
