Great thread! Although I`m not sure I completely agree in all cases. When working with folks I always give a handful of layout options including leaving the back blank vs. artwork on the back but that`s more for cost options. So far every client has gone with the 2 sided card for reasons of wanting to showcase their artwork. For an artist/photographer it`s like a pocket size portfolio you always carry with you. I guess it really depends on how many networking functions you plan to attend and how you want to use the cards.
CampSteve - I like your cards.
