-Hook size: U.S. 7 (4.5 mm)

Yarn:
-Contrast A: Debbie Bliss Rialto DK extrafine merino wool superwash, colour 84 (2.5 balls)
-Contrast B: Debbie Bliss Rialto DK extrafine merino wool superwash, colour 78 (1 ball)

A good substitution for the yarn is: The Baby Wool 100% baby Alpaca by We Are Knitters (Bordeaux colour for contrast A and Pearl colour for contrast B). I used a 4mm hook even though the yarn recommends 5mm. This yarn I found thinner and itchier than Debbie Bliss, but the person who I gifted the scarf was fascinated when hearing it was made with alpaca wool

Measurements:
