To sign "bottom" hold the dominant hand about six inches below the
non-dominant hand.
The non-dominant hand doesn't move. The dominant hand does a down-up-down
patting movement. The movement is in the wrist.
Think of "patting the bottom of a box."
Some people "circle" the dominant hand, but to me that means
"below/basic/beneath."

To sign "top," form both hands into flat hands. Hold the non-dominant
hand (generally) vertical. Then use the dominant hand to pat the "top"
of the non-dominant hand twice. In my example below I wish I had held
my left hand a bit more vertical, but then again this might be a good time
to point out that there is a "citation" version of a sign (the full, pretty,
complete, carefully enunciated version) and the "casual" (sloppy,
half-formed, lazy) way that most of us Deaf actually do sign on a daily
basis.

"on the LEFT side"
The movement for this sign is similar to patting a wall on your left. Pat it
twice with your fingers. The movement is in the wrist (not the arm).

"on the right side"
The movement for "on the right side" is as if you were patting a wall on
your right. It is an awkward little sign but it still the one we use.
