Neat hat Kelly! So glad you posted this coz I was just about to start a double knit hat from that pattern on patterncentral that you used but then I saw this method and was wondering if it was better.
I'm dying to try double knitting but... hey, did you notice that in the pattern they leave out casting on Color B? Isn't that a mistake?
It says this:
Cast on 162 stitches in color A.
If you want to make your hat smaller or larger, you can cast on a different number of stitches. When changing the number of stitches, check your gauge and multiply the number of stitches per inch by the desired head circumference. Multiply this number by two (you're essentially knitting two hats, remember!) and cast on the resulting number.
Row 1: With color A *K1, bring yarn forward, slip next stitch purlwise, bring yarn back*, repeat from * to * across the row. DO NOT TURN WORK!
Row 2: With color B *slip next stitch purlwise, bring yarn forward, P1, bring yarn back*, repeat from * to * across the row.
Am I missing something? Nice hat anyway! cheers, Vic
