<<Disclaimer: Verify this information before applying it to your situation.>> I have made the rice base play dough recipe, it became moldy in about 10 days. Does anyone know if this play dough can be frozen to extend it's life, how about adding anything to prevent the mold??? My 3 yr old daughters nursery school and I came up with a solution that I would make playdough 1 time per month for the class and then the class could still use palydough all the time and I wouldn't have to worry about my daughter getting gluten exposure. I want this plan to still work out, any ideas?? Beth
