I love magnet bookmarks- nerdy, I know. ;) I think they are really convenient and for me, they last the longest, and I rarely lose them. I decided I would make some of my own in honor of Valentine's Day. They were super easy to make - it took me a little less than an hour - and the end result was super cute!
Fold your paper in half and place the top of the heart along the folded edge. Trace the heart with a pencil, and then cut it out with a pair of scissors. You should now have a double heart that folds over at the top. Attach two adhesive magnets - one on each side of the inside of your heart. And you're done! You can place one heart on either side of your page and the magnets hold your place. :)
