I made a cookie sheet note board today. Really cute!
First, I used my Cricut to cut the letters using the All Mixed Up cartridge. (set to 1.5 inches)
Then, I measured out the paper in accordance to my cookie sheet size. (This step is very customizable to your paper, size, and how you want to design your note board)
I then attached everything to the cookie sheet using hot glue. You could also attach everything to magnet backing to be able to change it up for different decor, seasons, etc.
