I used size 9 circular needles. Turned out to be a child's sized hat. I would add to the number of cast-on stitches. Also, end sooner than the last 8 stitches! (Maybe end at 16?)
Size US 10 1/2 DPN’s (6.5mm)
Cast on 56 stitches(Knit 1 Purl 1) Rep to end for ribbing- join stitches so you are knitting in the roundRepeat for 8 rowsSwitch to a seed stitch (Knit 1 Purl 1) rep to end of row
(Quick tip: Reader GMC tried this pattern and said the following: “knit one round even before the seed stitch rounds and Kfb of the first stitch in that knit round to get an odd number so I could just go round and round in seed stitch w/o really thinking about it” That is a great, GREAT idea. Now I am kind of embarrassed that I didn’t think of that before!)
Repeat for 26 rowsDecrease by K2T at the end of every needle (every 11th and 12th stitch knit together)Repeat until you have 8 stitches, then cut yarn, leaving 12 inch tail
Pull the tail yarn through remaining 8 stitches, cinch tight, weave in ends.
