July's a popular birthday month - my Mom turned 47 yesterday (she started young - got married the day before her 18th birthday, had me the following March)
Buffy, did you make your box with the largest layer 9x9 or did you modify to 12x12? I want to make one with a 12x12 bottom layer but I'm afraid I'll mess up the calculations to make the lid fit right... maybe I should have my DBF do the calculations. He is a mechanical engineer.... He should be able to handle some simple fraction math
