My first self challenge was spinning some bfl/silk in the Butterfly Bush colorway thin enough to use as a single for a pattern asking for laceweight or light fingering yarn.
On Day 1 I happily spun up singles at about 24-28 wpi.
On Day 2 those singles were plied with some shiny thread
Then on Day 3 the plied yarn measured out to 404 yards as my skeinwinder wraps in 2 yard repeats.
And here we are on Day 4 all pretty and ready to rock 'n roll.
Knitting is not part of the Tour de Fleece but I wanted to get the project started. (Once I get this pattern from HeartStrings up on my website I will link to it. Meanwhile here is the link on Ravelry).
My next challenge is a bit harder but certainly not onerous -- spinning pure cashmere.
