Thanks to Holly at decor8, I've been clued into Spoonflower - custom small-run printed fabric! Sweet Heaven!! I've signed up for an invitation, and will be keeping my fingers crossed!
I could finally get exactly what I want for my bags, pillows, and clothing. My roomate would also really dig this, she's going to start making Blythe doll clothes for her etsy store, and complains she can't find prints small enough!
