What can I do with these jars?

I have several small salad dressing jars that I was saving to store my spices in, but I found plastic ones that fit my spice rack better. I don't want to dispose of the jars, but can't think of what I can do with them. I have stored some of my pantry items in them, baking soda, nuts, salts. What can I make out of them or how else can I use them? They are 15 oz., The lids are plastic with the name brand on the top. Any ideas would help. Thanks. :)
