You will need:
- Embroidery floss
Then, simply stitch the two halves together! I think a whip stitch looks cute, but you can use a running stitch or running back stitch if you want. (Also, I only used three strands of the embroidery floss) Leave the top open.
If you'd like, you can even add a pretty little embroidery to the heart- just make sure you do it before you sew the halves together!
The heart fits over the corner of the page to make an adorable book mark! How cute would this be with a few pieces of candy inside and a "Will you be my Valentine?" note?
