I was making dinner tonight, so I let Abby do all the measuring for the cookies. It went pretty well until she got to the flour. We almost had a batch of peanut butter cookies that contained only 1 1/2 cups of flour instead of 2 1/2 cups. She tossed on this blue apron before we started. Judging from the picture it doesn't look like it would have helped out that much if we had a big mess.
