Quilt Notes: The single quilt block uses two opposing triangles to symbolize the hour glass and then tumbles or rotates them in succession. But in the tiling pattern (scroll below), SPINNING HOUR GLASS does not seem to rotate so much as it walks a rambling sidewalk or garden path, which is a little more interesting. The design is a four-patch pattern illustrated in Maggie Malone's 5,500 QUILT BLOCK DESIGNS, where it is traced to back (in print, though probably not in time) to Nancy Cabot's (Loretta Leitner Rising) 1936 quilt column in the Chicago Daily Tribune.
For more time travel see VORTEX — for another spinning design, see WHIRLING ARCHES — and for the hourglass shape, compare with SPOOL AND BOBBIN.
Notice in the Cabot illustration (left) that she titled the design in the plural, SPINNING HOUR GLASSES and she is the oldest source we have.
