Tip: I created my calendar on MS Publisher, but you can use any word document. I save mine so I can use it year after year and just change the numbers, holidays, clip art, etc...to update it for the new year.
Tip: Un-do is the best product for getting off stickers or anything with an adhesive backing. It neutralizes the sticker for you to take it off and when it dries it's sticky again to reuse on something else. I love it for scrapbook pages when I change my mind. Or getting off stickers from my kids furniture.
My calendar goes from January to January so it gives me a month to create my next calendar.
