I've been reading lots of posts here and there about painting your belly for Halloween/etc. What kind of paint is best to use? I was thinking it would be a fun art project to let my 5 year old DD make my belly a pumpkin or something. I want to use something that will not ruin any clothes and will wash off fairly easily when we are done and have taken some pictures. I thought about using her washable markers...but then I realized 3 year old DS might think Mommy is showing him it's ok for him to use the markers to draw on himself or anything else (for now he knows markers are only for paper!). What about washable finger paints - would that work?
