Little helping hands.

Pour in all ingredients minus the Lavender. (No particular order… each time is different for us.. and it always turns out the same.)  
Stir until everything is mixed well.
Once the mixture is (mostly) clump free. Heat over MEDIUM heat.
Stir. Don’t stop stirring. After a few minutes it will start to clump up. (I’m magic! Purple to Green. hah. Different dough.. same step!)
Stir, Stir Stir.Just keep stirring until the Play Dough is formed. It willform one big clump.
Remove from heat, and knead by hand. (This is my favorite part! It’s so warm and squishy! hah) Once it's cooled down a bit, add a few drops of Lavender essential oil and knead again- to make play time a calming experience.


FAQ
This recipe yields about a cup and half of dough. 

I use this recipe for each color I make. 
As far as how long it lasts, as long as it is stored right, it should last at leas up to 6 months. I'd suggest wrapping it in plastic wrap (or a Ziploc bag) and then putting it inside your sealed container... and it could last even longer. Every sealed container has air, and air can dry out and/or mold your dough, which is why I suggest wrapping in plastic wrap first.
I do not store ours in the fridge, but I guess you could if you'd like.
