I received some roving from a friend of a friend to spin up.
She had traveled to a B&B in KY, MapleHillManor, which is also an Alpaca Farm. A knitter but not a spinner, she found me and wanted me to spin up her 4 oz. of very nice alpaca.
I spun up two bobbins, and S plied it. It was nice to spin with and has gotten me back into using my wheel.
Below is the plied yarn.
She wanted to knit a scarf with the yarn. The result is 190 yds. of nice alpaca yarn. I hope this is enough for her to make what she had in mind. I did weigh the fiber and it was actually 3.6 oz. of fiber. There was 4 oz. if you include the weight of the bag and labels it was packaged with, or maybe she had removed some. I have found when I spin up 4 oz. my yield is an ave of 220-240 yds. of two ply yarn.
It takes quite a bit of fluff to make yarn. LOL
Below is a rough estimate I found online of amount of fiber to get the yards you desire.
Lace = 2600+ yards per pound
Fingering = 1900 to 2400 yards per pound
Sport = 1200 to 1800 yards per pound
Worsted = 900 to 1200 yards per pound
Bulky = 600 to 800 yards per pound
Very Bulky = 400 to 500 yards per pound
