We’ve used fingering weight (fine) yarn for this hat but any weight of yarn can actually be used. Just match up your yarn with appropriate double pointed needles and work the increases until you reach the desired head circumference. For example, we “went big” as an experiment and used Cascade Magnum (a bulky yarn) and 10.0 mm double pointed needles and only had to increase to 40 stitches to get a hat for an adult head size.

And, even though this was intended originally as a hat for “Rachel”, it can be made for any and every person in your friends and family. Sizing help is given for a wide range of heads.
