I love this monthly menu planning calendar from The Family Homestead. I've used different menu plan forms in the past and I think this is my favorite. It's so neat, light enough on graphics that it's quick to print and I can see at a glance what we've been eating for a month. This clears up my refrigerator from the scraps of paper I was currently using for menu plans.
I usually plan my menus only 2 weeks in advance to coordinate with my shopping times. Saving these menus will end up being a menu-planning time-saver later, though!
