Do you like making things? Do you do it for money, or would like to? If so, you need a business card. These can be your best advertising, but we all know business cards are boring and get thrown away. I have toyed with plastic or etched stainless cards before - these are really cool, but cost a lot, and are not really distinctively "you".
Do you make goods out of leather? Then make a leather business card. Do you make handmade greeting cards? Then make your business card look like one of these! Even better, make one that is actually useful for whoever you're giving it to, so it CAN'T be thrown away. I'm into making electronics, so what better way to advertise my skills than an electronic business card. Here are two experimental "extreme" business cards that are almost impossible for someone to throw away - one in the form of a key ring torch and one card that actually dials me up by itself! This one has a computer inside with more processing power than took the first astronauts to the moon (No, I'm not kidding!), yet the main part costs less than 50 cents. I'm also working on one that plugs into a USB port on a computer so that people can email me directly from a link, or look at a portfolio of my work.
Even if these ideas don't grab you, maybe they'll fire your imagination to think how you could make a truly unique card that uses your skills and tells people how creative you are.
