...and this is the the first thing I created. A repurposed applesauce jar with a little label of paint on it. My method involved painting a freehand rectangle on the jar, then applying two additional coats when dry. It's a little bumpy, but I think that adds to its charm. For a more refined label you could use any rectangular stencil- a label sticker outline, painting tape, etc.- and you could even sand each layer lightly with a fine grit of sandpaper. Be warned though, if you fill the jar with granola your label might be easily overlooked as all your kiddos scramble to get to the contents within! (wink)

ps. If you have many containers to label and little time, you might consider buying a "blackboard label" on Etsy- like these. There's even blackboard contact paper, here!
