If you haven't heard of Spoonflower by now, let me be the 800th person to talk about it. Spoonflower allows you to print as little as an 8" x 8" swatch and up to five yards of fabric with your designs. They are currently in Beta, meaning you have to have an invitation to print, but watch their blog, as they say they are close to opening it up to everyone.
The design idea came from Wordle, which How About Orange got me addicted to a few weeks ago. It takes words from your web page, you pick a font and a color scheme and it goes to town. I will admit, I used their result as a template and redid it in Illustrator. My first reason being I couldn't figure out how to save a high-resolution version of it. And redoing it let me change some words, leave some out, rearrange some, change fonts and colors at will.
It reminds me of those junior high craft projects where you cut out "cool" words from magazines and arranged them in a collage for your friends. This to me is an excellent use of Spoonflower, since you truly can create a one-of-a-kind gift. And Miss Orange commented that my Wordle would make a great pillow and the rest is history.
