This pattern is super versatile. You can make it as small or big as you want, just know that the bigger you make it the more yarn you will use. Mine was about 63” and I used about 2/3 of a skein.

My gauge was 6 stiches across and 4 rows of DC = 3” x 3”

I used a N (10mm) hook and Caron Cakes yarn. I linked to a video in the pattern PDF on how to make WW yarn Bulky.
