This pattern is written for 60 pegs 1/2” gauge loom, but I have offered instructions using basic math and peg count to make this hat on any loom.
I used baby yarn but I used the technique that turns the yarn into a bulky yarn. So using a worsted or bulky yarn single strand will work just fine with this. It will take less yarn to do this hat with the worsted and bulky yarn.
I also am offering short video tutorial for the techniques to help make this hat. It isn’t a full start to finish tutorial, it simply shows the parts that are questionable. There is also some photo tutorials. The pattern is written out as well.
If you choose to take the math method keep in mind depending on the gauge you use will change up on the yarn you will need to use.
This is an intermediate pattern using decreasing, increasing, draw string bind off, modified bind off, purl, and EW.
