There is an error in the stitch count chart for the brim. Round 5 should be 124 stitches, not 120. Round 6 should have 31 popcorn repeats. Round 7 should be 155 stitches, not 150. Notice on the brim chart that one stitch is missing towards the end of Round 5; this is to get the correct number of stitches for Round 6.
