Go ahead and spell "D-O-T-S." Or you can use a "C" handshape
to show big dots on your shirt. Or you can use an "F" handshape (
classifier "F" ).
Or, after spelling the word "D-O-T-S" you could use an index finger and a
poking motion to show where the dots are.
DOTS: as in great big dots on a clown's suit: Use a "C"
handshape to show where the dots are.
You can show a bit smaller dots using an "F" handshape:
Note: if the dots were on a wall, you'd do the dots out in front of you or
in the direction of the wall.
