The majority of my knit and crochet hats are done for charity, therefore, I don’t have a way to measure the heads that will wear them. Sooo… my secret is to keep sizing charts handy!
Download my Hat Sizing Charts here! You’ll find 2 charts included in the download… one for crochet and one for knitting. Keep it handy in your phone or print it for your yarn bag!
Crochet is simple to size and the same chart can be use with any gauge, yarn weight or hook size.
The Knitting Chart will include cast-on numbers. This is great when you have a open skein of yarn and no plan or pattern in mind! After a quick glance at the cast-on numbers, I can knit a simple, basic beanie without having to go on a pattern hunt! (IMHO, this is perfect when the yarn needs to do the shining. I like solid colors for cables and fancy stitches.)
And speaking of charity work, there are several things to consider before jumping in! Click this link for a video I did a while back on the topic.
