Today I attended my first local event and last night I realized I didn't have any business cards. I wanted them to be like a paint chip you take from the store so I went with a square design (2.5"x 2.5"). Water coloring them was so much fun and very easy.
I like how they each look different and I hope they are memorable. There is nothing worse than a lame business card. That might be a slight exaggeration, but you should stick out from the pack so people remember you. A good test is if people comment on your card when you hand it to them or can't stop starring at it or feeling it... good paper will go a looooong way!
