If you are a creative person, you shouldn't have a boring business card. Here is how I made mine :
Step 1 : Choose your support ( I used black cardboard )
Note : Black cardboard will turn brown when carved
Step 2 : Draw your design on Illustrator or Autocad
Step 3 : Use colors (or layers) to determine what you want to cut and what you want to engrave
Step 4 : Set the laser cutter
Step 5 : Ad something unique (the backside of my card is made of sandpaper grid 150) It can be used for improvised DIY project.
