I wanted a lightweight yarn so I chose a #3 DK yarn in cotton. The stitches are breathable without being see through.
Cotton hats are not itchy on sensitive scalps. Getting outside and enjoying the sunshine can be so rewarding, and protecting your head is important.
When a family member or friend receives a cancer diagnosis crochet hats are one way crocheters respond. Crocheting a hat for someone who is enduring the difficult time of cancer treatment is such a great gift.

The Yarn
In order to keep this hat light, I am using Berroco Modern Cotton DK.* It’s a soft yarn that has a gorgeous sheen and comes in a variety of color choices.
I chose a neutral color and added a simple diamond pattern for a little detail. These are colors that I know the recipient really likes.
You can substitute another #3 DK / Light yarn. There are many soft baby yarns that are affordable.
