Some might say the boy is a boy of many hats. And that would be true in more ways than one. He is a busy one. His mind is full of play, invention, building, drawing, and playing some more. His hat he takes off. His hat he sets down. His hat we never set eyes on again. And as parents are want to do, we go out and buy him a new one. Because a boy needs his hat, you understand.
Now, today I decide that the buying of hats is in the past. Today is a good day for making hats. So I get out that old pair of Lo's jeans that I was saving for just such an occasion, and I get out some newsprint, and the hat-making begins.
First I measure the boy's head, and draw out a pattern based on the circumference of a circle: 2πr. I cut out the pattern, pin it on the jeans and cut out the denim pieces. I also cut out the same exact pieces from the small orange fabric square living in my stash.
I pin everything together. All the denim shapes to make one hat side, all the orange shapes to make the other.
