TOOLS AND MATERIALS
• US size 7 and size 9 circular needles (whatever length you’re most comfortable with) - you’ll be knitting in the round
o Using two (2) sets of needles is optional, but people seem to prefer the brim to be a little tighter than the body. You can change up the needle sizes to make slight size adjustments. 6s for the brim also work fine, but you may want to add an additional row of ribbing.
• US size 9 DPNs (4 of them) – or whatever size you used for the body of the hat
• worsted weight yarn in at least two (2) colors referred to as MAIN COLOR (MC) and BACKGROUND (BG)
• yarn needle, for closing the top
• crochet hook (optional, for weaving in ends)
• a stitch marker (optional, but recommended for the crown)

Gauge: As patterned, you’ll have approximately 4 sts/inch and 5 rows/inch for the body of each hat. This gives you a pretty average adult-sized hat. When lying flat, a long neck hat measures about 10.5” long and 10” across. It will stretch up to about 12” or a little more (20-24” circumference).
The t-rex hat is a smidge smaller, coming in at 9.5” across and about 10” tall, stretching to about 11.5” (around a 23” circumference). If you want to attempt a smaller size of either hat, try dropping a needle size or two for the body and/or using sport or DK yarn. The patterns are pretty stretchy but still be careful with your tension!
