Version 1 of the chemo cap: cast-on of 100 stitches, stockinette body, and 2x2 ribbing for the brim... covers almost all the ears.
I'm now doing Version 2, started it March 15 Sunday night... the body would be 2x2 ribbing, and cast-on is just 80 stitches. I'm varying the number of cast-on stitches because i read, belatedly after finishing Version 1, that tencel stretches even more than cotton. So I decided to reduce the cast-on to 80 stitches for Version 2, which is gonna be stretchy already being pure ribbing (except for the crown). My plan for Version 3 would be stockinette body with roll brim.
Tencel in itself being a shiny yarn is not easy to photograph even when it's cloudy natural lighting. Sorry for how my pics do not do justice to the sheen of the yarn.
