Freeform crochet and knitting
Freeform crochet and knitting is a seemingly random combination of crochet, knitting and in some cases other fibre arts to make a piece that is not constrained by patterns, colours, stitches or other limitations. The roots of this art are thought to be in Irish crochet, whose own identity came to the fore in the 1960s and 1970s.
