My crafty enterprises are not a business but a hobby. And yet I had great fun making some business cards for me the other day.
templates available in MS Publisher or any other desktop publishing programme. Ok, yeah, takes a bit of time to print and cut, but at least it is fully to your own specifications.
I even printed a nice design on the back of the card - not my own, of course, but a downloaded Chiyogami design from Canon Creative Park.
Happy designing, everyone!
