As a companion to the thread "Stretching pre-primed canvas",
http://forum.portraitartist.com/show...1&page=1&pp=10
where it was explained how to do this in writing, I am offering this picture tutorial. I just happened to have the camera handy today while stretching a 40" by 30" canvas for a commission.
The support being stretched is a traditional top qualty pre-primed linen that has been glue sized, and primed with a coat of lead white. It's relatively expensive, seemingly inflexible and unforgiving, but very luxurious to paint on. Linen is very different than cotton canvas, and pre-primed linen takes some additional getting used to. Being tricky to stretch without introducing unwanted ripples or stretching tension artifacts, I want to visually share a useful tip and technique of temporarily tacking each corner to eliminate those ripples and achieve professional perfection.
I am currently using Fredrix "Rix" linen on a six yard roll, and "Best" stretcher bars made by Jack Richeson Co. Other supplies are copper plated tacks, canvas stretching pliers (required), an ordinary hammer, and a tack puller. A packing blanket makes a nice work surface.
Oh, let me add as a safety and health precaution, PLEASE wash your hands after handling this lead primed linen. This is very important, as it will leave a slight dusty residue on your hands. Before snacking or lunch break, just clean up!
Let's get stretching,
Garth
