Isn't this the cutest thing? Probably the easiest as well! All you do is cut out two felt hearts, sew them together and you have a bookmark. They make great gifts.
Here are my felt heart bookmarks. I thought it would be fun to add some embroidery, so I added a lazy daisy and a circle of running stitch to each one.
Update: You can now download a free pattern for these bookmarks by clicking on the image below! Also, read more details in this post.
