Butterfly crochet 16
200g mercerised cotton

The “16” is on the side of the label… tricky taking photos of this gold gleaming label!

No official yardage provided.

On label it’s also listed “NA 14/6”. Means “Νούμερο Αγγλικό” = Number, English. This is a way to verify the yarn’s weight. Here: 1 g = 1.6934 meters.

In this case: 1.6934 x 14 : 6 = 3.9512666667 per gram and around 790 meters/868.41 yards per 200-g-skein.
