The earliest computer systems used punchcards adapted from knitting machines. Pop Punch is a collaborative conceptual project with a coder and a sound designer: between the three of us we’ve come up with a programme which converts the tracks of a vinyl LP into knitting patterns.

These pullovers are the melodies of the seven tracks of Giant Steps (1959) by John Coltrane, converted into seven knitting patterns. Each pattern is made up in Scotland as a traditional Fair Isle pullover using Shetland yarns. The pullover is styled after early 1960s knitwear, with contrasting long cuffs and a short neck rib.
