Painting supports

Where weight is not so much of an issue I make my own inexpensive panels using hardboard or masonite and three coats of acrylic gesso, with one coat on the reverse side to prevent moisture entering the panel.  

For travelling I make my own panels using linen glued to gatorfoam. This is the lightest possible panel.
Claessens Double Primed Linen
3/16" Natural gatorfoam
Neutral Bond glue
For more information on making these boards, see the Virtual Art Academy Process Building Block.

For a better quality support, I also use linen mounted on birch plywood from SourceTek.
