Here we have what I think is the 1st really modern form of the Hank of cord we so love! It makes an appearance early in the teens. It is still blue( this example is darker blue) and is fairly limp. The thickness has stablized at about the 1 mm. The hank is 4" long and approx 180" long total. The cotton construction remains the 3 twisted strands. This style of hanks is seen in sets from the mid teens mostly.
