Great ideas for old baby food jars

I did not have the heart to throw away old jars of baby food!  So I have a large box full of old Gerber and Earth's Best baby food jar tucked under our bed. I think there's about fifty pieces under there.

I'm really convincing myself that i'll have the time and the skills to actually reuse or recycle or re purpose them so i won't have to throw them away. Maybe that's the pack rat in me.
