My lost message was about 60 wt YLI. Bought some at a show. $5 for a thousand yards or meters, not sure. I do miniatures and the thread just disappears. It is the only cotton 60 wt thread I have found. The first time I wound a bobbin, I thought it would never be full. I was afraid the whole spool was on that one bobbin. I sewed all week without winding another. Order it from YLI.com but call order in. The Internet shipping price is based on money spent,not actual shipping cost.
