In April, I finished off 600 yards, although I had about three unfinished projects on the needles going into May.
For May, I did finish off two projects and almost finished my cardigan. Except I ran out of yarn for the cardigan. I need to order one more ball of yarn from Knitpicks to finish the button bands and the short sleeves. Although the cardigan is technically unfinished, I'm counting it out of my stash for May. I've slaved away at it for two months and used up all my yarn for this project. There's no way it's going back into my stash after this anyway. End total for May: 1165 yards
I have approximately 10,235 yards of yarn at home. Not bad. It's on the low side compared to most knitters.
Here's another stashbusting tip. Decorate gifts with pom poms!
