Just wondering if anyone has any tips or calculations or magic on sizing up and down hats. I know that using different sizes of yarn will change the size of the hat due to the guage. But what if I want to use the same yarn? Specifically, I have an awesome pattern for stocking hats- but the largest size I have it in is 6-18 months. I'd like to make the same hat in youth and adults sizes. I'm fairly proficient at crocheting. I'm even really good at math. But I can't seem to change up patterns. It's like a mental block!!!! I could spend countless hours doing some trial and error. But I know there's got to be some science to this I can apply!
Thanks so much!!!!!!
