This is all Knit Picks lace weight yarn. It's very inexpensive compared to a lot of others. This is heathery yarn and the colors are a bit light. The skein in the middle is actually very greeny-gray and the other two skeins are darker. I have twelve skeins of this, or at least twenty-four shawls.
This is Knit Pick merino lace weight. It's hand dyed (but not hand-painted, which is an important distinction). It's a very nice yarn and I like some of the colors very much. For some reason, totally unknown to me, I have thirty-eight skeins of this. I had forty, but I knitted the Angel Lace Shawl from two of them.
This is the Knit Picks 70% alpaca, 30% silk lace weight yarn. It's finer than the all-merino yarn above it. It makes a very pretty scarf, like the Forest Canopy Scarf I knitted from two skeins of this in turquoises. I currently have eighteen skeins of this.
I also have four skeins of a beautiful teal alpaca heather lace weight from Knit Picks. And I have four skeins (100 g, 880 yd) of their lace weight merino Bare, in natural.
I probably have more Knit Picks lace weight yarn than I really need.
Here's the lace weight yarn bin. It's a twelve-gallon bin from Costco and except for the apricot cotton at the back, the tangerine skein center front, the alpaca in the left corner, and the hand-painted Morehouse Farms merino in the bag and to its right, this entire bin is filled with Knit Picks lace-weight yarn.
I'm considering making about half of it available for trade or purchase on Ravelry. I've already sold about twenty skeins of yarn there. If anyone sees anything they'd like here, let me know.
