Alicia from Sew What Alicia shows how you can sew up a quick business card holder from felt. It takes just a couple of seams and few hand stitches. She made a bunch of them to give away with her business cards at an upcoming conference. If you wanted to make just one for yourself, you could splurge and use leather instead.
