Homemade Playdough
Source

Ingredients:
1 c. flour
1/2 cup salt
1 T. cooking oil
1 T. cream of tartar
1 c. water
Food coloring of your choice
Add-ins of your choice (i.e. spices, extracts, glitter, etc.)

Method:
Stir ingredients together well.
Just measure them into the saucepan you will be using to cook the dough, but mix them well before heating up the pan.
Over medium heat cook the dough, stirring constantly until it forms a ball.
(NOTE: When it starts to pull away from the sides somewhat and clump together and most of the “wet-looking” parts look dry, it’s ready to remove from the pan.)
Turn dough onto a board (or the countertop) and knead until very smooth.
(NOTE: It will be pretty warm to the touch, but try to knead it until it becomes a nice, smooth ball. If it feels sticky, you can work a little more flour into it and it will be fine.)
Cool.
Store in a covered plastic container OR in a sealed ziploc bag.
(ANOTHER NOTE: This dough does seem to always stick in the saucepan somewhat. I have tried spraying the pan first, but I still have a crusty residue on the pan when I’m finished. I am used to this now and just plan on soaking the pan after I make a batch. I just wanted you to know about that though so you wouldn’t think you had goofed something up if that happens.)

When I add spices, I usually start with about a teaspoon (though I never actually use a spoon).
I just shake a bunch in until I think it’s going to produce the desired level of scent. (I like a LOT of scent.)
If you are adding an extract like vanilla or peppermint, for example, probably just a teaspoon will be enough, but you can experiment with a little more than that.
Also add gradually if you are doing glitter.
I would still start with only about a teaspoon and go from there.

Homemade Stickers ~ NON TOXIC
Sourced Here

Ingredients:
1 packet (1/4 oz.) unflavored gelatin
1 T. cold water
3 T. boiling water
1/2 t. white corn syrup
1/2 t. lemon extract*

Method:
1. In a small bowl, sprinkle gelatin into cold water. Stir about 5 minutes until soft.
2. Pour softened gelatin into boiling water and stir until completely dissolved.
3. Add corn syrup and extract. Mix thoroughly.
4. Brush mixture thinly onto the back of picture that you want to turn into a sticker.
5. After it is dry, moisten to apply. You can just lick them since the ingredients are non-toxic and they taste great!

*You can use other flavors of extract….try coconut, strawberry, or peppermint for variation. We used almond extract for ours. I also placed the leftover adhesive in a small, covered, glass jar and placed it in the fridge for future uses. The mixture will gel, but when you are ready to use it again, just place the jar in a bowl of hot water for a few minutes and it is ready to apply.
