Purpose:
To help user avoid supine sleep.
Materials:
- Elastic strap approximately 3 cm wide
- Tennis ball
Equipment:
- Scissors
- Fixed blade or
lock-blade knife
Procedure:
- Cut off a length
of elastic a little longer than 1 meter.
- Tie the ends of
the elastic together (granny knot) to
form a circle.
- Use the knife to
cut approximately 3 cm long crossed
slits on opposite sides of the tennis
ball.
- Poke a loop of the
elastic near the knot through both holes
in the tennis ball (all the way through
the ball).
- Push the knot
inside the tennis ball.
- Pull and adjust
the elastic through the slits on either
side of the tennis ball to produce two
equal-sized elastic loops coming out of
the ball.
- Custom fit by pushing elastic into or pulling
elastic out of the slits on each side of
the tennis ball such that the elastic
loops go around the shoulders
comfortably, yet snugly. The elastic
should hold and center the tennis ball
between the shoulder blades.
Use:
Place arms through the elastic loops
such that the tennis ball is centered
between the shoulder blades.
Machine wash as necessary. |
