If you're like me, you can always use extra bags here or there. What about a bag to store up a few toys - one that you can just grab and go? I used the tutorial here to make one of my own.
One thing I changed was I finished the edges before starting to make sure there weren't any raw edges showing.
This one is quick and easy - and you could embellish it as much or as little as you want. Perfect nap time project!
