what do you do with your empty baby food jars, empty formula cans?  

For one glass food jar, I store push pins.
* one is for sequins
* one if for small hair bands
* i made snow globes one year with my Brownie Scout troop.

I was at a antique shop the other day and one booth has glass baby food jars painted pink on the inside. (for cute storage). they were really pretty that way.

As for formula, I simply recyled those.

I also made candles one year in the glass food jars as well for my sisters.

With formula cans you can use the 2 diffrent sizes for canisters for the kitchen (flour, sugar, tea, etc) or decorate and glue them on a board to put on the wall for kitchen untinsils or pens for a desk area. Baby food jars you can nail the tops under the kitchen cabnets to hold spices, just put spices in the botton and then they screw to the top so the dont use counter space. Also good for nails, thumbtacks, arts and crafts stuff. They also make good baby shower gifts, just fill them with m&m's and tie a ribbon on them, put them on the table for guests to take home. Think out side of the box, they can be used for alot! I love to upcycle stuff : )
