So if I reduce the stitches by, say, the number of stitches it takes to knit one inch - I would therefore reduce the circumference of the hat by that same one inch? That sounds easy enough. But will I need to modify the decreasing stitches towards the end of the pattern? If so, how hard is that?? I guess, since the pattern is in ST, I could simply remove the number of extra knit stitches evenly throughout the decreasing rows.
