This is how I made my clothespins, with used chopstick.
But if you re out camping you can use pieces of STICKS. (IT WILL BE REALLY USEFUL IN WINDY DAY!!!!!).
or you can use garden cane.
You can adjust the rubber ring ones you have hang your clothes.

Step 1: WHAT YOU NEED

YOU NEED:
-used chopstick (or collect little sticks of wood, long 3 inches and half);
-bicycle inner tube (cut in rings)

TOOLS:
-scissors;
-knive (or little saw).

Step 2: CUT CHOPSTICK IN HALF

Cut chopstick in half! Or go collect pieces of sticks, long 3 inches.

Step 3: PLACE RUBBERS RINGS

1-cut bicycle inner tube in rings, NOT TOO THIN.
2-put two sticks together, wrap around one edge a ring of inner tube, REALLY FIRM. (see picture).
3-wrap another ring in the middle of the 2 sticks, firm, but not too too tight (so it will allowed clothes to fit between the 2 stick).

DONE!
