A few years ago I had the bright idea to try my craft skills and construct a production item (my wife refers to this period of time as The Square-Circle Fiasco). Anyway, after swearing off prop-building for a few years, the bug has finally bitten me again. I'd like to tackle another Square-Circle (yes, I have dummy written on my forehead) but I was hoping for a little input before I lock myself in the garage.
What is the smallest S-C box you've ever encountered? I'd like to make a small one, but I'm afraid it wouldn't be as deceptive.
Any thoughts?

I have encountered on that is a "Pocket Square Circle" it fit easy on your palm. didn't even reach your fingers. and was about 3 inches tall. Was cute. Deceptive. No. Not really. It's didn't hold much (tube was a little larger than a film canister). So I would not back it anywhere near that size if you want it to be deceptive.

Magically yours,

The smallest I have ever had, used a 35mm film canister for the circle.

(That is about 1.5" tall and 1" diameter.)

Of course, it was near useless. You could fold up a dollar bill in it.

The Milson Worth small one I used to have had a tube about the size of a small soup can. I imagine any smaller would be very limiting.
