I'm finishing up the planning stages of my home theater and this includes acoustical treatments. Because this is in my living room, I can’t just go sticking foam blocks all over the walls, so these have to look good. Well I ran across this site that sells some, but are expensive.

I could make these myself as long as I can get some quality canvas printings.
Do any of you have experience with canvas?
Do some print shops have better quality than others?
Are any in particular recommended over another?
What resolutions should I be aiming to get for various printing sizes?

Another example.



And in case anyone is curious, it's canvas around 2-3" OC703 fiberglass with a simple wood frame and corner braces for support.

 

I highly recommend checking out PictureFrames.com. I ordered a print that was shot with a point and click and was really pleased with the outcome. They even support gallery wrapping.

 

I ordered two prints from Costco.
They came out great. Didn't touch any of my editing that I did.

Price is pretty competitive with most places you'll find online.
Also I got it delivered to my house using UPS only took about 5 days from the day I sent off the images.
