Help! My toddler thinks our walls are his canvas!

Okay moms, I need some hive mind help.

My little Callahan (2) has discovered crayons and he is OBSESSED. Which I love! As an art person I want to encourage it but omg… he thinks our entire house is his personal canvas lol. The walls are his favorite target right now.

We’ve tried the washable crayons (a lifesaver) and I set him up with his own little table with tons of paper but he always sneaks away to go decorate the hallway. I feel like all I say all day is “on the paper, honey!”

what did you guys do to get through this phase?? Any magic tricks I’m missing? I’m going crazy with the magic eraser haha. TIA!
