I saw this mentioned on a photography site today and I thought it was brilliant. The site is based in Europe where I guess they are even more dependent on IKEA for cheap furniture and thus even more sick of the, well, IKEA-ness of it.
The site prints artwork as decals you can use to cover your IKEA furniture and give it a fancy designer look. Or if you’ve got the flair, you can use your own artwork or photo as the design.
