Rainbow is an even 2 ounces/60 yards and spun of 100% merino & gold metallic thread. The rainbow colors flow throughout the yarn and waft in and out nicely! It is from a sports weight to a worsted weight with a bit of bulky thrown in for good measure! This would be nice as a knit or even woven into an art piece! Gentle hand washing in cold water with wool wash is advised to prevent any felting, shrinking or fading.
