I want a yarn line

First, I'm knitting a scarf. A basic seed stitch scarf, nearly 12 inches wide, on size 3 needles. It's "boy" colors, black, blue, green, and grey. No I don't have an intended recipient, I'm trying to pass it off to a friend to give to her brother or boyfriend. It's very pretty, and fun to do, even if the needles are so small and it is so wide! Yeah I'm crazy.

I've been dreaming of my own yarn line. There are so many yarns out there that people pick and buy just because they are pretty. I do that too, that's why I use wool and soy singles, I know they're not the best thing for my project. But there are projects and ideas that could be done better if there were another yarn available. While learning to spin I've studied different ways yarns work, and what is better for projects.

-Crocheters perfer yarn that is Z twisted so that it crochets better and doesn't start to untwist as you're hooking.
-For weaving, I would love to have super overspun yarn for collapse able wefts. There are a few of those yarns available, specifically from New York based Habu, but they are very fine, I want one I could use with 8-12 ends per inch warps.
-Cabling yarn is spinning two two plies together back in the direction of the single. This can wear well and create a better yarn for socks or other high wear items.
-I've recently used a discontinued yarn that had an acrylic core with wool around it, when I felted it, I got this wonderful bumpy fabric, the acrylic didn't felt and shows up still in the stitch formation but the wool fills in all gaps.

I'm sure I could think of more yarns that are missing from the yarn market, and I think you can too.
