My little one LOVES stickers!! She cannot get enough!
One day while I came up with this idea and she literally sat there for a good 30 minutes!
I took two big sheets of white paper and taped them to our wood floors (if you only have carpet - I have also done this by taping paper to our glass doors).
I drew a few things...her name, some shapes, etc.
I then gave her a sheet of stickers to do with as she pleased.
She LOVED it! I left it on the floor for a day or two because she kept going back and playing.
