My work tends to be contemporary and I like a clean look.
I have my framer make a simple frame in 6"x 6" and
5"x 7" sizes. It is a tidy and consistent presentation - I like that.
Once framing issues are resolved the problems of small work have a lot to do with scale and using brushes in a size that will maintain the same "painting voice" that appears in larger work.
I try for as few strokes of the brush, as possible, to create shapes that will hold the integrity of the design - as opposed to pulling out the tiny brushes and - well, you know - trying to see how many angels can be painted on the head of a pin.
With small paintings I work for more disciplined brushwork that leads to a straight forward, loose and non-fussy end product.
These pieces are painted on 1/4 inch gatorboard - which is the same type of support I use for all of my work.
The gatorboard is cut to size, gessoed on top and sides, painted as I would any other piece, except to make sure that the sides get attention as well, because they will show. Once the paintings are dry, they are glued onto black foam board so they appear to"float" in the frame.
