Quilt Notes: this ARROWHEADS block was the design chosen by Nancy Cabot for her quilt column (really an old-fashioned quilt blog) in the Chicago Tribune on March 1, 1933. Slightly different than the pattern in Rhoda Oscher Goldberg's QUILTING AND PATCHWORK DICTIONARY, this one uses isosceles triangles in the arrow corners, producing a classic, geometric elegance, with an almost circular secondary tiling design (dodecagon, see below). For more on quilt designs, which create circles utilizing only straight line see, OPTICAL ILLUSIONS FOR QUILTERS, by Karen Combs (1997).
See also a completely different pattern with the singular name, ARROWHEAD at this site. For more information on the ARROWHEADS quilt block, browse Related Sites.
Here are more examples at this site of blocks with secondary "circular" designs, created by
straight-edge polygons in the tiling pattern:
BEAUTIFUL STAR (dodecagon)
BLOCK STAR (irregular dodecagon)
GRANDMA'S SURPRISE (octagon)
JAPANESE FLOWER (irregular dodecagon)
PIGEON TOES (octagon)
