Decided that even a thin hat does not fit under my helmet, so try this to protect my ears on the bike from the cold.
Just casted on 80 stitches with 5 mm needles this time and did 8 repeats of row 5, as suggested here.
Fits really good, even with a big head like mine. Now I will have to try this when cycling. I still have app. 130g of that yarn left, will do more I think, now a more pink strip is coming up. Took me about 2 hours to knit this and I got 2 dout of half a ball of yarn, so it is app. 25 g per headband.
Did the test under the bike helmet today, worked very well! Might want to do 10 repeats of row 5 instead of just 8 next time.
