  1. found you through another site, but I have a question:

    you said you used hand soap to make it, did you use that INSTEAD of the detergent?

    dish detergent sounds like the powder…and the instructions say that as well. So I guess I’m confused because of your handsoap comment. :/

    Thanks for clarifying. (email addy is with my comment)

  2. Bree, I used the hand soap in place of the detergent – it smells better. Dish detergent works just as well. My kids tend to break out easily so I wanted something more gentle for them.

  3. My kids are going to love this! I think I will use baby soap in stead of regular soap. Thanks!
    .-= Lisa´s last blog ..Thankful Thursday =-.

  4. We are definitely going to try this one- we have bathtub markers but they are running out! She loves painting in there though- so this will save the day!

  5. We’ve been making bathtub paint for years and use a similar recipe but a much lazier way. 🙂 All I do is mix up little cups of mild shampoo, a few drops of food coloring and a spoon full of corn starch. I don’t cook it or add water or anything. They paint on the walls and then wash it all off. It’s easy frugal fun!

  6. I was looking for the information, keep it up.

  7. Found this through pinterest! I am interested in making this for my nephews for Christmas, but I have a question. Will the food coloring stain their skin? Is there another alternative if the food coloring stains or did you find it washed right off of their skin?

  8. Magnificent site. Plenty of useful information here. I’m
    sending it to some buddies ans also sharing in delicious.
    And naturally, thank you on your sweat!
