The year of cold sheep started well with no yarn or fibre purchases in the month of January.
I managed to use up 162 yards of commercial yarn in a pair of mittens

and another 1,248 yards of handspun yarn in a short-sleeved dress

I also spun 200g of fibre into 766 yards of fingering weight yarn.

Total yarn out: 1,410 yards
Total yarn in: 766 yards
Net yarn reduction: 644 yards
Fibre stash reduction: 200g.
It’s a start.
