SUNDANCE debuted in print in L. K. Meecker's QUILT PATTERNS FOR THE COLLECTOR, 1979. Barbara Brackman's ENCYCLOPEDIA OF PIECED QUILT PATTERNS lists the pattern (#2864) along with related designs, comparable at this with RISING SUN (see links), and LIGHTNING IN THE HILLS. Maggie Malone locates SUNDANCE in her "Nine Patch Patterns" category, #1098. The design is highly unique, however, and though it's name might not seem unusual, there is no other block called SUNDANCE except this one. It's really very special.
The dance itself manifests best as a tiling pattern — see below, and where an unexpected octagon plays a central role (evoking a similar pattern by Nancy Cabot called EMERALD BLOCK, dated April 22, 1936, but without Cabot's diamond in the center, see right). But what a glorious and playful sundance this is!! The block seems to suggest both a dance among worshippers celebrating the return of the light of the sun, as well as the sun itself, that is, its intermittent appearance dodging and dancing, whilst peeking in and out between the clouds.
