If the project involves paint it is pretty much guaranteed to be a home run in our house. I promise our lent crafts will not include so much mess. Just remember they are only little once and use washable paint.
This project has been a long standing favorite of my kids.
A Pepper with the top cut off length wise and de-seeded.
Large (I recommend heavier stock) paper
Simply squirt a desired amount of paint in the bowl. Give each child a pepper and paper and go to town. Even my 18mo old got in on all the action this year. He got a bit messy but it was all worth the smiles and giggles.
