Well, I did confess about the crayon last night to him. He just rolled his eyes. The magic eraser did work on the crayon. Took a bit of time, I think I can still see some of the writing, but maybe over time I'll just "forget" where I did that at. The embossing powder is still there, didn't budge it. I grabbed a used dryer sheet (was I suppose to use a new dryer sheet?) and ran the iron over that on the board, the iron is nice and clean but the embossing powder is still there. I think at this point it's there for good, at least it's not coming up on other fabrics.
