Cookie sheet calendar

Saw this idea for a cookie sheet calendar probably a couple of years ago, I can't remember where and when I saw it, but a big thanks to who ever came up with the idea, because it is great.......... 

So I decided to make one for my daughters sewing teacher as a year end thank you gift..........

All the paper is stuck to the cookie sheet with sheet magnets.....you can buy these at any craft store. Stored on the back of the cookie sheet are the rest of the days, and months, so you can switch it around for each month and each year......... 

Thanks for looking :)
