I also have about 4 pounds (ie: 16 skeins) of a lovely 4-ply Aran wool. It's not as CRAZY soft as the single-ply I usually sell, but it's nice and pretty soft and it's CHEEEEEAP!!!
$7 a skein, including the postage!
Gauge: Worsted weight four-ply, Aran type 4.
US Needle #8, 4.5 stitches = 1", 18 stitches = 4".
Again, the list of colourways is here:
