McMorran Yarn balance
McMorran yarn balances, indispensible! Everybody has one, right?
But I have three in the studio where I teach, and I don't know how to tell if they are metric or "American" inches. I thought I read somewhere that you could tell by the color of the foam cushions inside, but the Halcyon web pages shows green foam in both the metric and conventional balances. Or they used the same picture for both...
We have two grey ones and one green one. Anybody know how to tell the metric from the inch ones?
