I love starting scarves with a few stitches and knitting until my yarn is optimally used up. Diagonal sideways knitted triangles are fantastic, but unfortunately they are asymmetrical.
Compensation compensates this deficit with a leftover of a bright contrasting color.
The unusual method of picking up stitches makes sure that the scarf is reversible.
You need 100 g of yarn of the base color and 15 g in contrast color.
