OK. So i'm done spinning the Ingeo. It WAS an exercise! Every yard of it. But a good learning experience. I liked the look of it more that the feel, but i'm beginning to like the feel too...
I'm just going to quote from Knitter's Review from people who've spun this before just to save to time because their descriptions are bang on target. Here goes:

"These are SLIPPERY fibers, you may have noticed. I happen to like slippery fibers. Lots of others don't.
What you'll do is put a lot of twist in, and spin more slowly until you get the feel down. You'll find what often happens with slippery stuff like this is it puffs up again. So put more twist in than you think you need, and once you've got a little length on your bobbin, unwind a bit and let it ply on itself. See how it's MUCH thicker? That's why. Keep that in mind while you're spinning. "

"I've found these fibers want to be spun fine at a high ratio. Ingeo get a cottony feel and can be very unforgiving. I found the tencel to be the easiest to spin and I hated silk latte which was somehow both too sticky and too slippery all at the same time. I use a supported long draw with a bit more tension in the back hand then what I would use for wool. Blending wih wool will definately make it easier to spin for you."

"Vi,
hope this helps....when i first spun ingeo, i hated it.
However, I found out that if you strip it into 8-10 thinner rovings, it gets a lot easier - doesn't stick as much. Spin at a high ratio (and not too fine) because if you plan on plying it with itself, it'll drift apart while plying & be a nightmare if spun on a low ratio.
I have a big gorgeous skein of Ingeo I spun recently (will post images of it on my blog soon). It looks fabulous & feels pretty silk (tho' not in the same way as silk). It took a long time to make but if i was to do it again, i would be wiser to learn from the mistakes i made & save time."
