Long-tail twisted cast on - stockinette with 1st stitch slipped at the beginning of every row as follows:

Row 1: Slip, SSK, Knit to 2 st. before end K1 f&b, k1
Row 2: slip1, purl to end.

Came out really pretty, love the gradient, it’s so gradual with no harsh colour changes. The thin yarn on big needles makes a wonderful, soft and drapey fabric once it’s washed and blocked.
