10 years ago I was inspired by something that @hotdogsladies said about only having a certain number of Saturdays with your kids and I created this project to help me remember that idea. I put 521 marbles in the left jar and every Saturday for the last 10 years I've moved a marble over. There's been a lot of change in our lives and it's been a lot of fun watching the kids grow and become very cool adults. Now, on to the next 10 years!
