Well, maybe not entirely DIY, but you get my drift. :-)
One of the very first Postcrossing cards I received was one that the sender had had made from one of her own photos. That this was possible hadn't really occurred to me before, but of course, it's a brilliant idea. I have quite a few very good shots that I would love to do something more with than 'just' posting them on my blog. :-) So I started looking around for someplace where I could have some of these made into postcards.
I first thought I should try to find some Norwegian option, and some googling led me to Ifolor.no. I'm not sure that I'd ever heard about this company before. They advertise photo products of the highest quality. Their prices seemed pretty good, so I decided to check them out. They offered a ten-pack of cards from each photo uploaded. I used two different photos, and I ended up paying about 130 crowns (postage included) for 20 cards.
Production and shipping was quite quick, my cards were in my mailbox after one week.
The quality however ... meh. I wasn't entirely happy with the quality. The print is too grainy and the color reproduction isn't as good as I'd hoped. I've been using the cards, of course - they're certainly good enough to send, and I've gotten very positive feedback on them - but I will not be ordering from this company again.
