This is an off set triangle scarf, starting with 2 stitches,and always increasing.
The scarf is knitted in a rib pattern, and the drop stitch magic doesn’t happen until you cast off.
For the cast off, allow at least twice the amount of yarn that you usually would.
The yarn I have listed has a lovey weight and drape to it, yarn can be substituted, but it needs to be a smooth yarn that isn’t fluffy so that the drop stitch can travel the length of the scarf.
