Ferrico Hat Pattern
15 sts = 2 inches and 48 rows = 4 inches in Brim pattern.
25 sts and 35 rounds = 4 inches in Body pattern
For the Brim Pattern, the row gauge is more important than the stitch gauge.
Because of the slipped stitches worked every other row, the column of knit stitches will appear to be only 24 rows.
