Medium skills. You need yarn (Organic cotton from Stoff & Stil is: DK, 8 ply, 11 wpi. 200 grams. I am not sure of how many meters/yards you need since the producer doesn´t tell, but 440 meters or 441,2 yards is probably enough), needles (4 mm/US 6) and a piece of fabric for the backside. Knitted back and forth. Two sizes: small to medium and large to x-large.
