Step 0: Conception (the kind involving ideas, not haploids).
I needed Zombie History Month greeting cards to distribute, as promised in the informational zombie history pamphlets I'd already passed out, by way of the zombie history information centers.

Step 1: Production
Unsatisfied by the available zombie clip art, I was prompted by my partner in life & tasking to use my own modest powers of illustration. So, I did a quick line drawing, scanned it & added some color & text.
I happened to have a "greeting card making kit" which consisted of perforated card stock, envelopes, & some less than helpful directions. I used my amazing powers of cognition to figure out that whole printing-on-both-sides-of-the-page-and-making-sure-everything-goes-in-the-correct-direction thing.

Step 2: Making it Purchasable
In preparation for the task I'd purchased a .99 cent card. I scanned it, cropped down to the barcode & printed some stickers.

Step 2.5: Assembly
Some folding & stickering took place.

Step 3: The Drop(s)

For this part, I enlisted the help of my Lovely Assistant. We meandered to the first location & amused each other by opening various musical cards & sharing feelings of repulsion, disgust, & horror at the dissident & ghastly tones that emerged. He blocked the cashiers' view of me while I made the drop & documented. The proceedings at the second location (which by the way, belonged to the same chain as both the store that the barcodeclonecard was bought from & the one that the first cards were dropped in) were much the same.

There's a bit more detail included with the images.
