Quilt Notes: For an illustration of this design of FLYING BATS outlined on a full grid, along with general instructions on how to draft your own patterns, see the QUILTING AND PATCHWORK DICTIONARY by Rhoda Ochser Goldberg, 1988. Two variations with a diamond set are illustrated in Barbara Brackman's ENCYCLOPEDIA OF PIECED QUILT PATTERNS.

Listen to the sonar of a horseshoe bat (wav, 368K) from www.batbox.com.
The STRINGENT COLORS of the quilt illustations attempt to imitate these other-worldly sonar bat sounds.
When the design is tiled (see above left and below), the image itself creates an unusual geometric vibration. For another design with beautiful sound effects at this site, see RAILROAD CROSSING.
