This is a block I actually finished quite a while ago. It really is an easy one to do until you get to the applique part. That's where mine was neatly tucked away in my Week by Week Sampler binder along with a piece of fabric for the applique.
I have no idea why I didn't do the applique. I do it all the time, big or little or tiny.

If you're not a big fan of tiny applique, you could embroider the school bell or even use a little button. Another option is a piece of light weight Ultra Suede fabric. You don't have to turn under the edges when you applique with it, can cut perfect points and use a paper punch for a perfect little circle. It's also washable so there's no problem mixing it in with your cottons in a quilt. I've used Ultra Suede lots of times and have a stash of colors I bought as scrap bags. Makes great little black mary-jane shoes for Sunbonnet Sue and lots of other itty bitty applique shapes.
