You will need:
* Access to a laser cutter
* Note cards and envelopes. I used 3x5 cards. You can find them at an art store like Blick, Utrecht or Flax. Lighter colors will generally give you a subtler contrast to the monogram and darker colors will produce a stronger contrast.
* ~20 small weights (I used sections of T-50 staples)
* Painters tape
* Blank newsprint or butcher paper
Step 1: Design your monogram and etching template
Begin by creating outlines of the cards and envelopes of the appropriate size. The outer dimensions of your cards should be listed on the pack. I used a caliper to measure out the flap on the envelope. Create your desired monogram graphic in the desired location on the card and envelope. I would suggest making the card and envelope designs different colors so you can set a different laser power. When you're happy with the result, copy it in a grid so you can etch multiple sets at once.
