Abstract: Initial pattern data (50) and gauge data are stored, the pattern data is converted into knitting data based on the gauge data, and a knitted product is test-knitted. Sizes of the test-knitted product are compared with sizes indicated by the initial pattern data (50), and the pattern data or the knitting data is corrected. The correction amounts for the pattern data or for knitting data for two sizes are stored, and interpolation or extrapolation is performed based on the stored correction amounts to correct pattern data or knitting data for other sizes.
