www.misterart.com has it. You only use the Rabbit skin glue as a ground for linen canvas with oil paint, and the new acrylic/marble dust white gessos are what most professional artist use now and are more archival.

You can order it from most specialist art shop...but... nobody uses it anymore except some painters that want to do it the "very old skool way". Today's modern synthetic glues are better, keep longer and are very cheap.

Hi, The use of rabbit skin glue (sizing) is used when instead of using an acrylic primer (also known as gesso), one is going to use an oil primer. The oil primer cannot be used directly on raw canvas. Nowadays I guess that some artists are using PVA glue instead of the rabbit glue. Be sure it's a good acid free PVA glue. Now, the rabbit skin glue is dry and in pellets. You need to soak it in water and then warm it inside another thing with water, not directly on the fire (I don't know the name of that in english). It cannot boil. It's like making a pudding, but not in the oven. If you have any more doubts, ask at the Oils forum from the Wetcanvas site. Kind regards, José
