After searching for new sources of artist canvas, I came across wholesaleartsframes. Com
They have the best price- that was easy to see.
Of course as an artist I'm also very concerened with the quality of the canvas. I had asked them questions on several different occasions and requested additional close up pictures for the stretched canvas. My emails were replied to in a professional and timely manner.
I ended up making a $2500+ order for large canvases (mostly 2.5", 1.5" deep).
I just received my order and couldn't be happier. The canvas is thick and stretched very well.
The corners are nice and tight and the frames are braced and packaged safely.
Whether you want the best price, or am more concerened about quality- I'd recommend them.
