Uses for Spice and herb jars

I've acquired a number of empty spice jars - the ones with holes in the lids to shake the spices or herbs out. 
What do you think of using them for sowing small seeds? 
I have difficulty sowing seeds thinly, certainly can't sow them in a row, its not in my nature.   Tomorrow I will experiment. 

I'm sure these jars have other uses too. Let me know if you think of any, please.

Reuse them for dried herbs, cinnamon sugar for all that lovely bread you get.
