A little bottle of lavender oil lasts forever and is a great addition to craft supplies. This dough is such a favorite in my house because it is very calming for the kids (and me!) to play with.
Emma helped me to add all the ingredients (except the water, 1/4 c of flour and the flowers) to a large bowl. Once she was done I boiled the water and poured it in directly on the salt. That is my little trick to help disintegrate the salt.
Once it looked like this we dumped it onto a cutting board. I kneaded, adding the remaining 1/4 cup of flour a little at a time, until it was soft, but not sticky.
