According to this description, you can knit a hat of any size: children’s, teen’s, adult male and female.

Very important to knit sample and calculate the knitting density, and the number of loops that need to cast on.
The calculation is very simple, and gives a 100% correct result.

The hat will be very comfortable!

In this pattern I show how you can make an even elastic band and then continue knitting hat on circular needles.

You can use thicker yarn, and thicker needles

I wish you to have a good knitting fun and have one more handmade accessory in you wardrobe!
