The shells were glued on this board along with the two fish and lavender aquarium gravel. They were glued on there with an obscene amount of hot glue. The Dad was able to take a towel and break them loose quite easily. He needed the towel because although beautiful, they can be quite sharp.Dancer has made it her quest to get the glue off of all the shells. She is using a little screw driver and prying it off. She has only stabbed herself once ........ so far. It is making me nervous but I am trying to take a hands off approach and let her do it.
