Crochet Pattern: Drawstring Beanie with Yarrow Flower

Since this summer, I’ve been writing a monthly guest post on charity crochet for Oombawka Design Crochet. The Drawstring Beanie with Yarrow Flower pattern was originally published as one of those posts, and I’ve updated the pattern to include four additional sizes.

This post contains affiliate links. I may receive compensation (at no added cost to you) if you make a purchase using these links. The yarn for the sample was generously provided by Lion Brand.

While this pattern was originally designed as a “chemo cap,” it works just as well as a cozy hat for anyone in the family. If you do choose to make a “chemo cap” (with this, or really, with any pattern), keep in mind that soft yarn and minimal seaming are kindest on sensitive scalps. As some patients have heightened chemical sensitivities, you may also want to consider using organic yarn. I used Lion Brand Nature’s Choice Organic Cotton yarn for my version, which is now discontinued.

Since cotton yarn can shrink unpredictably, I designed this hat to feature a drawstring tie that keeps it firmly on the head. I also added a small yarrow flower embellishment. Many cultures around the world have historically associated yarrow with healing and health.
