- Cut two strips of paper 1" wide
and about 20" long.
- Lay the strips perpendicular to each
other and overlap at one end and then glue or staple these ends
together.
- Taking the strip at rear, fold it
over the front strip. Then take the second strip and fold it
forward over the first. Continue folding until the entire length
is folded according to the illustration. To finish the chain, glue
the ends.
- Pull the ends to open the ladder.
