Hopefully this is somewhat self explanatory for the most part. Basically you just need to pick a cover (there are 4), click on the image so it is full sized, save it, then print it. Now, it should print on well on a 8 1/2 x 11" sheet of paper. If it comes out wonkey at all, and you think it is my fault (heh), let me know!
I would suggest getting at least a 3" sturdy binder (one that has a plastic sleeve on the front to slip in your cover) and a box of laminated sleeves to slip these into. For sections such as "Household Tips & Tricks," you would probably file in some magazine clippings or recipes for homemade cleaning products. Same goes for the "Wish List," section. This is a section where you can tear out magazine pages or print out products from the internet that you'd like to buy later on.
Amy at Momadvice (which you should check out!) has a great section of downloads that would be perfect to go in a household planner.
