Old corner bookmark featuring a pair of orange-bellied birds

Pictured above is the front and back of an interesting triangular bookmark that I found in the bottom of a box of used books. The seam on the back of the bookmark has come unglued, but it still does its job just fine, slipping over the upper-right corner of a page.

There are some good websites — including Jovers and Tally's Treasury — that show you how you can make one of these bookmarks yourself.

Of course, if you want an eco-conscious and super-quick corner bookmark, just cut the corners off an envelope you've already received in the mail. And you can still go ahead and decorate it any way you like.

The bookmark in use on Sarah's James Bond book.
