I dont' know what I was thinking. I recently bought my son an art easel and last night I set up it for him. He got super excited and wanted to draw on it right away. So I gave him a washable marker (green). I went into the kitchen to put away some dishes and I came out and saw that he scribbled alllllll over our couch cushions! Our couch is light tan (almost white)! I died. It's still green. It won't come off! I thought it was washable!

I guess I shouldn't have let him color by himself. Do you always supervise your LOs when they color?
