Jamie Wyeth uses them. Alex Katz uses them . Linda Brandon and I use them.
They make beautiful custom stretchers. They will stretch primed canvas for you or stretch it raw and gesso it. They will do gallery wrap style as well. They have different weights of stretchers available also.
Their service is amazing and the quality top notch. I have used them for years. The prices are not unreasonable. It is for the working professional.
