I am sharing a pattern for a scarf I made to use up some of my stash.
This pattern is written in simple terms and has not been tested (I am not a pattern designer)

Worked in the round on circular needles.

Approx. 200g of yarn needed, 100g in colour A and 100g in colour B.

Finished scarf measure approx. 44 x 5 in with a gauge of 21sts x 28rows to 4x4 in

I used a Fibonacci sequence to design the striped pattern.
