I do oil sketches sometimes on unstretched canvas or canvas paper from a pad. Since quick oil sketches can be
sketchy with their success rate, it's an inexpensive solution. Of course, if you have to mat and frame them under glass, there go any savings you may have had.
But what to do with the successful ones you'd like to frame? I mount them on acid-free foam core so that I can varnish, and frame like any other painting on a panel.
What you need:
~A
sketch you think worthy of framing, (the hard part)
~A
clean flat space to work on (also a challenge in a busy studio, this table is in the thinking corner of my studio, and I keep a clean sheet around for projects like this)
~
Acid-free foam core, about 1 inch larger than your piece
~Old but
clean piece mat board or foam core larger than your painting (I used the back of an old canvas board)
~An extra piece of
mat board or foam core larger than your piece
~An
Exacto knife

Rubber brayer
