They are perfect for storing craft supplies like buttons, beads, small scrapbooking items, pencils, hardware like screws, nails, washers. I'm with you on the idea of not recycling or throwing them in the trash, would rather reuse them. You could use chalk paint and label each jar. Do you bake? If so then the bigger jars would be good for storing extra flour, sugar, baking soda, etc.

I use a lot of recycled glass bottles to hold craft supplies. I remove the labels then add chalkboard labels available in the craft store.

I saved pasta jars and use them to store bulk spices that come in plastic containers. Now they stay air tight and look good with the new lables.
