I used the 72 and 88 peg 3/8” gauge looms to create this hat pattern. But I have written a formula on how to make it on any loom and any size you would like. It is an easy pattern and has several reference videos for all the steps in the hat. I used cascade yarn pima cotton to create this bonnet. This was a commissioned hat that was done for someone who has cancer and will be going through chemo. So it is a great bonnet for someone who may need a hat for that. It also has photo tutorials and written instructions.
