The first not-me knitter for the PoA Scarf Knitalong is Trista. She says she's doing a PoA Gryffindor one. She sent me a link to Beaverslide Dry Goods and recommends their yarn as an alternative.
She writes:
"I've used Beaverslide Dry Goods merino yarn, and though my scarves are a bit 'fluffier' or 'fuzzier' than the ones on Lauren's site, the yarn is wonderfully soft and fun to knit with. I can't reccomend them enough if you've not tried them. (http://www.beaverslide.com/) I'd reccomend the 90% merino 10% kid mohair with two skeins of each color, using Alpine Spruce / Frosted Smoke (Slytherin), Prairie Coneflower/Charcoal (Hufflepuff), Winter Rosehip/Prairie Coneflower (Gryffindor), or Glacier Blue/Frosted Smoke (Blue/Silver) or Glacier Blue/Chokecherry Heather (Blue/Bronze) (Ravenclaw)."
