From the Etsy page:

Rachel yarn makes the most delicious socks and scarves imaginable! Incredibly soft as only merino can be, with a pretty little twist to it. Great for stitch definition, and wonderful to knit with. 100% superwash merino wool, 2-ply, it is a true fingering weight yarn. Rachel yarn is a pinch thinner than Penny yarn. It’s almost too pretty to use for socks. It would make great scarves with no itch attached. You have to knit with it to believe how lovely it is! Lovely for baby items, too.

Rachel is dyed with quality acid dyes

100 grams; approx 400 yards.

Fingering Weight: 7-9 sts/inch, size 0-3 needle. If you decide to knit scarves with it, you can easily go up a couple of needle sizes.

100% superwash wool.
