Well Dave, here is my contribution to your Summer Spinning Challenge:
It's not much but it did get me to spinning again and i will spin more from now on.
I spun 13 different colors up into this yardage:
469 yards multi color merino 12 wpi
251 yards black super wash merino/silk bits/black alpaca 11 wpi
151 yards fall colors BFL 6wpi
380 yards green BFL 16 wpi
102 yards bright multi colors cotswold / x bred merino 10 wpi
738 yards all colors alpaca/silk/cotswold/baby shetland/merino-polward x bred 12 wpi
256 yards dark blue denim super wash merino 19 wpi
161 yards dark blue denim super wash merino 17 wpi
113 yards multi color merino/cotswold 11 wpi
41 yards multi color cotswold 12 wpi
148 yards dark blue denim super wash merino 8 wpi
42 yards multi color cotswold 12 wpi
600 yards light steel grey superwash merino 17 wpi
that comes to 3304 yards in all,they are all two ply so i guess i spun 6608 yards in singles.
not even close to yours but it's the most i ever spun in this amount of time.
this was fun, it really got me spinning again, thank you.
