This skein looks sort of like the skein in the last post, but it's really a new skein. Honest. It's really the second skein of unknown yardage and grist, awaiting measurement and a plan. Sometime. Mostly I was just tired of looking at the stuff and wanted it spun up and into the next phase of waiting for attention.
I was asked recently whether I spun for spinning's sake or whether I spun to have yarn to use and actually used it. The answer sort of is "both". I spin because I like to - it is a different process and product than the rest of my fiber activities. I usually don't start spinning with a project in mind, but often by the time I have the first skein done, a project has come to mind. This project often has to wait for a while because I have other projects in the knitting queue ahead of it. As long as I still look at that yarn and see that project as one I want to do, I keep the yarn, but it's in the knitting queue not the spinning queue now. If I look at the yarn and no longer see that project as one I want to do, there's no longer any point in keeping the yarn. About once I year, I purge the yarn closet. Skeins that are left over from finished projects (I believe I did mention overbuying for projects once or twice before), skeins that were from interesting spinning projects but which didn't result in yarn that elicited a desired knitting project, and skeins such as these from overpurchase of fiber wind up in a box to Manhattan. These particular skeins may very well wind up in hats meant for Dulaan, but if I don't get to them within a year or so, they'll wind up in a box elsewhere. I don't see any point at all in cluttering up my closet and my mind with unplanned for yarn; someone should use it for something useful.

This is a yarn that has no particular project in mind. It's spinning project, meant to stretch in a different direction and has been a great deal of fun. This is a three ply 100% Bombyx silk (Chasing Rainbows). (Obligatory dime picture below.)

This skein is about 380 yards and is approximately 2 ounces of fiber, so should be approximately 3040 ypp. Ok - that's well into the laceweight range. The second skein is in the works.

And then we have "Homespun" (a product name I truly despise), my version of same. Mine is alpaca and leftover silk single. The silk single is from the three-ply above. The alpaca was ripped through as a fat single (one of these fill a bobbin with poorly prepped fiber in 15 minutes or less deals). Plying took another 15 minutes. But! I don't have to look at the single or the fiber anymore, it will make a nice warm thick-thin cap for somebody which I will felt a little bit (I'll do something with it - I wouldn't foist this yarn off on anybody) and it was a nice temporary change from the fiddliness that is silk spinning.
