As a matter of fact, yes.  Yes, I'm going to wear that apron in the library and here's why...
1. Making is messy.
2. Here's to the end of calling myself from the library phone to find my cell phone.
3. Who needs to see the sauce spot on my shirt from my lunch?
4. A granola bar is just what a teacher needs to wolf down on between classes.
5. It's always handy to have a pen and post-it notes to jot more things down on the endless "To Do" list.
6. Librarians are always "cooking up" something, especially during book tastings.
7.  Pockets are perfect for holding change for kids who forgot their lunch money.
8. Students can scan the QR code on my apron to access their Flipgrid of book recommendations.
9. If students are already late to their next class, don't waste time by finding a hall pass.
10. Book fairs can be busy, and an apron can help you be organized.

I just love this photo of my co-author Stony Evans and his co-librarian during a book tasting.

Here's a cool hack:
Use Wakelet, Buncee, or Flipgrid create a digital cookbook. Then print the generated QR code on an apron. You will have access to a wonderful collection of recipes whenever you scan a QR code.  What a wonderful gift for a teacher if each child submitted a recipe from their culture.
