We bought a roll of lining wallpaper yesterday in anticipation of doing some outdoor painting and Harry just couldn't wait to get on with it this morning! The paper is thick enough to roll out on the grass and be treated quite roughly without ripping so it's great for this.
They used sponges, brushes, cars and toy animals plus their own feet and hands and had a great time!
I love the rainbow footprints
They also enjoyed painting themselves but wanted to get inside quite soon after this as it started to get chilly, so I brought out some buckets of water. Harry said he was the artwork and I had to hang him on the wall, but get him down to feed him!
