ah Fred
.. another reason I love my spray bombs.. I have them all stacked in a box, colors up.. reach in, grab one in each hand, start circling the plugs, and have at it.. don't like what I see.. reload, or mix 'em up
...
seriously tho.. I usually write my schemes down, as I usually paint everything at once... load my racks with the ones I'm gonna do multiples of, and shoot 'em all at once.
