I love mason jars.
Actually, I have a mason jar obsession. Ask my roommate...she will back me up on this.
I purchased some Classico sauce and what do you know...it COMES in a mason jar. Jackpot!! When the jar was finished I the soaked and scrubbed the label off then ran the jar and cap through the dishwasher.
Once clean, I sprayed the tops with 2 coats of Rust-Oleum Specialty Chalkboard Spray Paint and let dry overnight.
When I need to use the jar I always label the top with Pentel Arts Wet Erase Chalk Marker. When it's empty the writing comes right off with a wet paper towel and the jar can be re-used!
Oh, and aren't they adorable??
