This is a floppy, 5.5in brim sun hat with slits to allow for over the ear headphones. The headphone holes have elastics to close by themselves. There is a 6in slit on each side of the hat above the ear to allow headphones to be put through. I designed this for myself so I could wear noise cancelling headphones with a big floppy hat due to sound sensitivity. Handy for people with sensory issues, such as those with Autism or ADHD, especially if you can’t wear ear buds/ear plugs. There is guidance to adjust for different head sizes, but not full instructions. To do it in rainbow like i did, I got 1 skein of each colour.
