Here are the yarn bases I regularly stock:
Sparkly Merino Sock - This 4-ply yarn is made of 92% superwash merino and 8% lurex. There's enough lurex to really sparkle without compromising the softness of the merino. The neat thing about lurex is that the sparkle shows even more on darker colorways. This comes in extra-large 115 gram or 4-ounce skeins with a total of 409 yards, so it's on the heavier side of fingering weight. Sparkly Merino Sock tends to dye up brightly. This can be hand washed or washed on a gentle cycle in the washing machine on cold. It should be laid flat to dry. Uses: Knit, Crochet, and Weft in Weaving.
So Silky Sock - This yarn is lusciously soft! It's a 4-ply made of 50% mulberry silk and 50% superwash merino. It comes in 3.5 ounce or 100 gram skeins with a total of 438 yards per skein. So Silky Sock tends to dye up fairly softly. I recommend washing it by hand in cold water because of the silk content, though there's nothing that will felt in this yarn. Uses: Knit, Crochet, Warp and Weft in Weaving.
Sock Perfection - I have finally found the perfect yarn base for actual socks! It is a fingering weight that combines 80% extra-fine 19.5 micron superwash merino with 20% nylon. It's a good solid 4-ply yarn that comes in 100 gram skeins with 450 yards per skein. It can be machine washed on cold and air dried. It tends to take the dye rather brightly. Uses: Knit, Crochet, Warp and Weft in Weaving.
Cashmere Sock - Cashmere Sock is a lovely luxury yarn perfect for everything from shawls to socks. It's made of 80% superwash merino, 10% cashmere, and 10% nylon. It's a 4-ply yarn with 435 yards per skein. It tends to take the dye at a medium level. I recommend washing it by hand for greatest longevity. Uses: Knit, Crochet, Warp and Weft in Weaving.
Buttery Soft DK - This is a wonderfully soft 2-ply DK base with great stitch definition. It's made of 45% extra-fine merino (non-superwash), 45% baby alpaca, and 10% silk. It is a dream to work with! Each 100 gram skein contains 245 yards. This should be washed by hand in cold water and dried flat. Buttery Soft DK dyes up softly. Uses: Knit, Crochet, Warp and Weft in Weaving.
Squoosh DK - Squoosh DK is a squishy, soft, stretchy yarn made of 100% extra-fine superwash merino. It's a 4-ply yarn that comes in extra-large 115 gram skeins with 250 yards. This can be machine or hand washed in cold water but should be air dried. Uses: Knit, Crochet, and Weft in Weaving.
Handspun Yarn - I spin worsted-weight, bulky, and super bulky handspun yarn, but each colorway is its own creation. I typically use some combination of merino, polwarth, BFL, alpaca, tussah silk, mulberry silk, muga silk, sari silk, kid mohair locks, teeswater locks, camel down, yak down, angelina, and firestar in my handspun yarn. All of my handspun yarn should be washed and dried by hand. Uses: Knit, Crochet, and Weft in Weaving.
I have a few other bases I rotate in and out, but
