On a tangent, does anyone know where you order custom cards from? I have always wanted 3x5 cards with a little bit of white space on top (for a title) and then isometric graph paper for the rest.
Any good printing shop can do that. Just search for "custom index cards", there are usually more than enough results to even order them online. At least in my country. Though, it seems index cards are a bit more pricey than the more popular prints like posters, post cards or business cards.
