this is my mom's play-dough recipe... slightly adapted.
pretty much i just added lavender essential oil and left out the food coloring because i love the natural white coloring.
1 cup flour
1/2 cup salt
2 tsp cream of tartar
2 tbsp oil
1 cup water
15 drops lavender essential oil (optional)
a few drops food coloring (optional)
mix all ingredients together in a large frying pan. cook for a couple minutes on medium heat. as soon as the play-dough begins to pull away from sides remove from heat (it will still be a little bit gooey). place on a sheet of wax paper or straight on the counter if you want. knead well. store in an airtight container. i always save yogurt tubs for this. the container pictured bellow works perfectly, it is a recycled finger paint container.
note: you can use any essential oil you want but i would stick to the mellower oils if your making it for children. do not use peppermint or eucalyptus oil if making for children.
