For the past year, I've been knitting for others every so often through Ravelry's Will Work for Yarn group. In that group, people send you yarn to make them something, and also send you the equivalent yarn as compensation. The last project I've done through that group (probably the last I'll ever do) used a full skein of Wollmeise Lace-garn.
This is one mile of yarn. I made a shawl using a full mile of yarn.
Yarn: Wollmeise Lace-garn in We're Different (probably Mond im 7. Haus)
Timeframe: May 1 - September 27, 2017
Now I have another skein of the same yarn, in a slightly different colorway, for myself. Another full mile of yarn - maybe another Nuvem?
