PrintablePaper.net is one of the most popular FreePrintable.net sites, and because I’m always getting great suggestions from users, I’m always adding to it. The most recent printable paper additions include a mileage calculator chart, an annual budget planner, and Wulff net paper, (graph paper of a sphere projected onto a plane.).
There’s also an entire new category: printable postcards. There are full-color, illustrated postcards for marriage announcements, moving, and events. Download both horizontal and vertical postcard backs: they are preformatted with spaces for a postage stamp and addresses. Print on both sides –cardstock is great for mailing. The PDF versions are free, and you can get the editable DOC (Microsoft Word, Google DOCs, etc.) versions are $4.
