Here is the cake and cupcakes we made for the party, in the plant stand turned cake holder.
The first activity that the girls did when they arrived was make a glitter shell necklace. I picked up a bag of shells at the dollar store and added a bail that I had found lying around. (You could also drill holes in the top, since the shells from the dollar store aren’t “real” shells and don’t crack like the real thing.)
The girls added a stripe of glue, and then some glitter, and repeated for each color they wanted. The one my daughter made is below. It such a simple idea, but the girls LOVED it.
