I would suggest either using new paint brushes or running your paint brushed through the dishwasher.
The "paint" will most likely be tested by your little artists.
The room smells so good while you are painting and the smell lasts for days/weeks after it is dry.
Once it's dry it is a little shimmery and has a sand paper like texture. The sticky is mostly gone when it's dry but the awesome smell is still there.
Add the leaf and the stem and you have a cute little pumpkin.
