First I got some metal sheeting at the craft store. You can probably find it at the hardware store too. I added a ribbon to the back using some tacky craft glue. Then I covered it with some scrapbook paper, but you could also use contact paper or even wall paper.
Then I made some simple magnets. I bought some clear "squished" marbles at the craft store. Print the days of the week and glued to the bottom of each marble. Then I glued a magnet to the back of each. I printed some of my favorite recipes onto 3x5 cards. Now all I have to do is choose the recipe I want and put the magnet with the correct day (the day I want to serve that dinner) on it. Super easy to keep track and the recipe is right there. I can also use it with recipes I find and print online or rip out of a magazine. Plus, if someone else starts dinner they have all the ingredients and instructions right at their fingertips.
