I love when a customer I've worked with through the years comes to me and says, "I need some notecards. I like red and elephants." Creating small sets of custom notecards is soooo much easier than it was when I started designing. Once upon a time, everything had to be printed offset, which meant making a plate and producing a large enough quantity to make it worthwhile. Now I can easily print off a batch of 20 in black on my printer (still adding color by hand to each and every card) and everybody's happy.
