If you have a sewing machine - these are super easy. I just used a Microtex needle (skinny needle) and sewed right across the note card top. Word of advice: simple is better. I got a little too excited trying out all my different stitches and thread colors - and the results were not great (see the middle card as an example). You can buy a pack of blank cards for less than $5 at Michaels - a pretty quick, easy, and inexpensive way to make custom Thank-Yous.
