Today I followed through with an idea I had to make a triple condiment dish. Not sure about the knob. Might try a double dish next and may use pinched pots instead of these layered pots. When I lived in Florida I remember I made a double one with pinch pots and little spoons to match. We shall see. One week we are freezing at night and during the day and then today it got up to 62 F. Not complaining though. Thanks for reading and for all your comments.
