First, let me apologize for the photo quality--it was a rainy dreary day and I had to shoot inside with incandescent light--ugh!
For the third and final technique, I chose the Caladium colorway (none in my shop presently--I think they're still packed from the move!). It's a deep green/teal/ruby batt that I love and that will go with many things in my wardrobe. The technique for spinning these is a semi-woolen technique. Start by rolling the batt into a sausage shape--widthways if you want striping, longways if you want more of a blend. I want a bit of striping so have gone widthways.
You then begin to attenuate the roll, stretching it out in stages until it's a fat roving. I usually start at one end and gently pull the roll with one hand while holding the roll with the other. Keep enough distance between your hands that the wool will slide easily--it shouldn't be a tug-of-war!
Once you've gone from one end of the roll to the other, start again and work back to the beginning. This way, you achieve a more even thinning of the fiber roll as we all have a dominant hand. If you continuously start from the same end, that hand will overtake the non-dominant hand and eventually pull the roll apart completely (yep, did that once or twice!).
You will continue thinning the roll till it's the thickness you like. I like mine to be about 1-1/2" wide because I will spin with a long draw to trap air in the yarn and that's my preferred prep for the technique. If you haven't done the long draw, you probably want to practice before spinning sock fiber until you're comfortable with the preparation and the spinning technique.
Finally, I'll roll the lengthened batt into a ball of roving. Actually, since my batts come three-to-a-bag, I split one of them in half so that each ball of roving is actually 1-1/2 batts-worth of fiber.
Next, doing the actual spinning......
