Let's assume that if the jewlery box were 1" square, you would NOT
make a floating panel and just glue the top on. Given that, it stands
to reason that somewhere between 9" or so and 1", is your belief that
cross-grain gluing ceases to be a problem.

Can you tell me where that point is? At what length do you believe it
ceases to become a problem as a practical matter?


AFAIK there is no written rule however the answer to that question is more
dependent on climate conditions and the variation of those climate changes.
Basically, with experience you will find a rule of thumb that you are
comfortable with.
