A tessellation of chevrons rotating around hexads, triads and diads (p6 symmetry) with thick outline spacing and rainbow subdivisions - like whirling paragliding kite wings. Currently displaying red-centred rainbows on white (at a very reduced scale!). Other colours, sizes and orientations are available on request and you can even ask for a combination of several designs together.
The apparent glitch in the design is an artifact of Spoonflower's recompression of the image when adding the rulers. See their unglitched preview using the link in the embed text via the option under the main image.
