Late of course but hey better late then never.
So here are my stats:
Yarn used: 19,623 yards
Yarn bought: 8,403 yards
Yarn Gifted: 7,869 yards (yep i was gifted a lot of yarn last year)
Since I was gifted so much my net difference is only -3,351 yards. Its totally ok though since those who gifted me yarn are amazing people.
I did spin up 17 oz of fiber and was gifted 12 oz. =)
ETA: I just checked and last year I knitted the most yardage since I started keeping track! Yeah Me!
