Here is a great way to bring the family together and be creative. This will build memories and open up conversations. I recommend allowing each artist to be an individual and allow for them to paint what is in their heart. You can pick a theme though make it broad as to not direct anyone on their ideas.
Create a Family Artwork
Buy a canvas from a local cheap shop, and some paints and get together to make an artwork together. Once complete, have it framed and display it on a wall in your house. It will make a great talking point in your home.
