These are AMAZING to give to families. You can customize them any way you'd like with Presidency information, teacher information, important dates to remember. ANYTHING and it's sized as a business card so you can get hundreds (yes, hundreds) printed for about $10. I've used Vistaprint in the past and have not ever had a bad experience.
Included in the download is an editable sheet of 10 that you can cut out yourself and also a single blank card that you can edit and then upload to a company's webpage and order business cards. You choose.
