The size difference is that for the 24 month you use a size 5 needle (instead of a size 4), aiming for 13 stitches = 2 inches, over the Aran pattern.

Requires 388 yds. of our soft and easy care U.S. organic cotton yarn. Using the classic Aran stitches, and adding a fun tassel on top, you can knit this in a 12 month or 24 month.

The hat coordinates perfectly with our Aran baby cardigan.

Level: Experienced
Recommended needle: U.S. 3 circular needle or U.S. 5 circular needle (for larger size)
