Another hour and a half, or so, last night enabled me to clean up the accidental "slops" in preparation for the application of yellow distinctions this evening and tomorrow (Saturday) evening. 90 minutes seem to be a good length of time in the painting chair for yours truly with, occasionally, two full hours. That is a short enough span of time to avoid an attack by the dreaded tedium demon, yet long enough to make some visible progress on whatever I happen to be painting at the moment. What about you? How long do you typically like to spend in the painting chair? At what point does additional time beyond that become counterproductive?
