Diaper Stacker al la Butterflies

I had been wanting to make a diaper stacker for my sister, but hand't actually set my nose to the grindstone. After all when you have a list of things that needs doing, items not on the list rarely get done.  But all that aside I did find time yesterday afternoon to make this.  The directions I found said it took the person half an hour.  Well clearly I wanted more than they did, so mine has piping and a gathered ruffle as well as the butterfly and dragon fly patches.  It was worth all the extra work of that I'm certain, but it took all afternoon, half an hour - right would have be nice.  Anyway inside is a sleeve and within the sleeve is a piece of my old hand-me-down cutting mat that had split.  That holds it open so no need for a bent piece of cardboard like my stacker had.  What do you think, to much?  Just right?
