I have just returned to machine knitting after a gap of 20 years and my memory is not what it was! I have two punched cards, which I once used to make a baby shawl in a tuck lace effect stitch. I cannot recall the needle settings but I do know the pattern came from Machine Knitting something, in the December 1979 issue.
Does anyone have a copy? It was a square shawl, the centre being knit from one card and the edges from another.
