I brought this crafty idea to brownies and, with 17 girls, we made bleach resist shirts.
We put on stickers and freezer paper stencils, then sprayed bleach on.
Within 10 minutes the girls could pull off the stickers and then "colour" in with fabric paint pens.
I can see us doing this quite often, for ourselves or for gifts.
I had the clorox bleach pens too but they were forgotten so I am eager to try those out.
