QOOP now allows orders for photo printing from Canadian addresses - meaning I can order stuff from Flickr, and have it printed as calendars, posters, books, T-shirts, etc... I just ordered a 13.5" x 19" poster containing all 757 photos I've published to Flickr (or at least as many that fit nicely on a poster - it couldn't fit in all of them, so dropped about 20 photos from 2004).
The process was pretty painless and simple, but has one rather large drawback: it's spendy. Not for the printing, but for shipping. The $9 poster cost $15 to ship.
