Nearly every source of attribution for old crochet patterns found on the web remains a mystery. There exists a dark web of pattern swapping enthusiasts fostering a contagion spread that conceals its origin. But one source identified is the old Russian language Duplet Magazine – worth singling out for its graphic ordering of patterns in optical monochrome cells configured to its own space-filling logic. Close-knit windowpanes create a comic strip story of evolving symmetry – a biological taxonomy of tiny skeletal organisms – Haeckel’s Radiolaria or Baricelli’s number-shaped organisms? Duplet really leads a double life as a handbook of space-group morphologies.
