Dear Nancy,
Regarding keeping track of stamps, would it be possible to attach
larger/longer handles on the stamps, so that they didn't fit easily into a
pocket? Also, I've seen stamps that were permanently fixed to a surface, a
little like a bridge, and paper was inserted under the stamp. A number of
these stamps could be attached to a carousel for easy selection. Just a
thought. Hope it helps.
