Mason Jar Lid with Holes
I remixed this for the purpose of making a Montessori-style learning toy for my baby daughter (by dropping stir-straws into the holes). However, it could be used for many other purposes such as a sugar/salt/herb shaker, or it could be combined with a piece of cheesecloth to make a strainer of sorts. So, I thought I'd throw it up here and you can figure out if it's useful! ;-)
