Here's the castle we made for Brenton's Medieval Days project. He and Glenn built it the night before Glenn left for China (thank you, thank you!) and Brenton finished up by mixing drywall plaster and sand (in my kitchen--hence the MESS) and covering the castle. I stepped in with my glue gun to help with the grass and we chopped the head off a dinosaur for the Loch Ness monster. One of those projects when you breathe a HUGE sigh of relief to see it finished and not be ugly.
