Scotchdown Yarn

Hello everyone im new! I just bought a bunch of yarn from a thrift store including 9 balls of scotchdown wool yarn but I don’t know anything about them. Can anyone tell me about them?

I’ve never heard of it. Is that the name or a description? Any other info on it? Since you found it at a thrift store and might be discontinued and those are occasionally hard to find info on.

The label seems pretty old. So all the information on it is scotchdown unshrinkable wool by lewis, moth proof, kelpie processed, dirt resistant and colour clear. The label is also just made from paper theres no plastic or anything with it which helps me assume that its an older yarn.
