I made up a new batch of playdough recently. For the green, I added what I thought was a lot of peppermint essence to make it smell nice. It still just smells like playdough. Here it is with a picklebums duck puppet and some dried kidney beans:
E called the grey playdough, "moondough", because it looked like the moon when I rolled it into a ball and she does like all things 'space'. I added silver glitter to that one.
I also made blue and yellow. It keeps really well in zip-lock bags in the fridge.
