Mark, if my inventory is correct, I probably have 11,612 flats, but like you, I have some difficulties to locate precisely and rapidly 20% of them. Like Eric T., time has come to start giving them away to collectors and painters who would have a better use than keeping them in closed boxes in a cave, as my pleasure is ultimately their painting, not collecting them But my speed would let me finish them during the years 2400's AD!
High time to review my strategy.
