Cool kitchen tip

I got this tip from one of my forums

The plastic top from a Parmesan jar will fit on  canning jars... powdered sugar, baking soda for cleaning, just a nice alternative to the plastic jar. 

It will fit on old mayonnaise jars also.

You can use the lids on the quart jar for hot chocolate mixes and the kids won't be as apt to spill when they spoon some out...   It will also fit on pint jars... even use the half-pint for your spice mixes.
