I used gesso but according to wiki (http://en.wikipedia.org/wiki/Gesso) "it is unwise to paint in oils over acrylic gesso because—unlike time-tested alternatives such as rabbit skin glue—the oil paint will eventually delaminate from the acrylic gesso surface".
So I went googling for rabbit-skin glue but this is what I found:
"Rabbit skin glue is considered to be a major cause of cracking in oil paintings by most modern conservators. Because the glue is hygroscopic, it continually absorbs moisture from the atmosphere, causing the glue to swell and shrink. Over time, this constant flexing causes the brittle oil paint to crack. Modern substitutes for rabbit skin glue are available, such as Gamblin’s PVA size [2] and Golden Acrylics’ GAC100. These substitutes do not have the hygroscopic properties of rabbit skin glue, while still being very slightly hygroscopic, and should not cause the damage to oil paints that rabbit skin glue does. However, these modern replacements do not stiffen and tighten the canvas as well as rabbit skin glue does, so some artists still prefer to use rabbit skin glue."
What should I use? :/
