Buy an orange or small clementine and a couple small containers of "whole cloves." You'll find them in the spice aisle and ours were 99 cents for a small package. Pop the cloves stem-in into your orange during craft time. They're actually easy for little hands to pop in once they're shown how.
And after your craft is done, it makes the kitchen smell lovely. Here are Woodjie and Rose's creations sitting on my windowsill.
