Another good item for the ever-growing "How to make a memorable business card" category:
Sean writes -I work part time as an organic chemistry tutor. I designed this laser-cut business card to include a drawing template to help my students with one of the most difficult diagrams they must master in o-chem. Both the forward and the reverse image (obtained by flipping the card over) are useful. For those wondering, the diagram or "chair" in question depicts a "saturated 6-membered molecular ring". Hit up Sean's site for more info - business card/drawing template page
Having a strong card design can be extremely helpful - If you're brainstorming, consider some card concepts we've covered in the past.
