Some time ago I knitted a lace collar from an old German lace pattern. For this cape I used the same pattern with less stitches and thicker yarn. I used a provisional cast on and first knitted the cape. Then picked up stitches again and knitted a turtle neck. The cast off is a picot bind off. For the turtle neck I arranged it, so that each knit rib ends in a picot.
For the yarn I used 3 balls of ‘Eco Alpaca Wool – Slim’. with 3mm needles.
