Well, that's what I'm doing tomorrow, but it will be for my living room. It's a 135x242cm piece of wall, which is a not as a square ratio as the image, so I had to crop it from its upper left corner down. Inkscape exported it to a 666MB PNG (ugh) I don't know why. So let's see...

That's really cool, if you get it to work, do a 'show HN' for sure.

How large are the sections that you're printing? And how are you printing them?

It's one section only which is 15945x28583px. I'll have it printed at a shop near home which is specialized in large printings for cars and trucks. Their printings are like peel out stickers.

It wouldn't be cheap but I definitely could do that, 17" wide strips of photo paper aligned very carefully.

I'm pretty sure you can get custom wallpaper printed.

There are companies that have canvas printers. Look for those that print on work cloth for other companies.
