Hi Happy New year.
I had white card paper in the armoire where I have had strange red stains.
I found dark spots on the paper and when I smeared was hard to smear with a wet napkin it smeared black. The thing is I have black crayon marks just above it on the underneath of the shelf (actual crayons, long sorry)this has started to peel and the wax fall off.
I suspect the marks could be from the crayon but wanted to make sure it wasn't fecal.
