I think the artist says it best----"What a sweet way to brighten your day! This lovely butterfly is made from resin and plastic beads in red, orange, and yellow. I threaded fishing line through a small drilled hole and hung it from a suction cup. Perfect to decorate any window - in your kitchen, bedroom, classroom - or take off the suction cup and hang it from your rearview mirror!"
