Since I am utterly incapable of book monogamy, I always have several half-read books lying around, and sometimes I don't have enough bookmarks to keep my place in all of them.
I chose to sew my bookmarks by hand with embroidery thread, which is a bit more decorative than the near-invisible machine-made stitches of the bookmarks that inspired me. I also chose to make them a different color on each side, for a quirky twist. What do you think?
This is a very simple, and quick project, and the bookmarks would make great gifts, favors, or stocking stuffers.
The one tip I would make sure to follow, is to assure that your hearts make a right angle so that they'll fit snugly over you book pages. This is easiest done by cutting them of of the corner of your piece of felt.
