I used the highest ratio on my double treadle Lendrum with a looser tension than I would normally use. I tried to keep the bobbin evenly filled with such a fine singles. By placing a small strip of cardboard on the bobbin and then evenly filling it, I was able to find a singles end in the event the thread snapped. This was extremely helpful, as I think if I hadn't done this I never would have found the end.
It was difficult to get started, but after I spent a little time working with it, it was most enjoyable.
Now I'll need to full this (cringe!) before it's useable!
