I print all of the pages that go ON the cookie tray, on standard printer paper. Then I print all of the pieces that require magnets to apply to the trays on card stock paper. To help go through the file and know what needs to be printed on standard paper and on card stock, there's a formatting trick! (Maybe you've picked up on this by now!)
I currently have 3 different themed cookie tray packs in my TpT store. Click on the images below to find them in my TpT store!
