question: postcards from your photos

[journalface.livejournal.com]

hi, crafty ladies. i want to make some postcards from photos i've taken on my travels. i've been looking around at different sites that do this, but was wondering if anyone here had any experience doing so. if so, i'd like some reviews of sites you have used (quality vs. price, design options, etc). if you have a good diy method of creating postcards from photos, i'd love to hear that, too!

thanks in advance!
