My favorite kind of client is someone who continues to need help with projects. This client came to me needing a 4-page mini-catalog to sell screenprint apparel. The result is shown below.

A little while later they needed a 2-sided flyer for disposable glove sales.

Then it was a scratch-off card to encourage sales among customer service representatives. Sell a case of gloves and you get one card with a minimum prize of a $10 gift certificate. A silver scratch-off circle was applied over the white circle, just like a lottery ticket. That would entice me to sell more.
