W&T means wrap and turn... here's how you do it:
slip the next stitch pwise wyib (pearlwise; with yarn in back)
yfwd (bring the yarn forward)
slip the stitch you just slipped BACK OVER to the L needle
ybk (bring the yarn to the back, completing the "wrap")
TURN the work, like at the end of a row
So for this pattern, you will
slip 1 stitch knitwise with yarn in back (like normal)
WRAP around the next stitch and TURN the work
Purl 8 across (these are the 8 knits you just did)
The W&T is use for short-rows, and allows you to add extra rows in the middle of a piece: If J'Lo was knitting a bikini, she might add some short rows to help make it long enough to go around her booty.
If you just turn w/o wrapping, you'll still have short rows, but you will have a gigantic hole in your work. (and then the booty comes out, yikes! :shock:) Amy has a video and picture in the advanced techniques section, under "short rows with wrap"
does this mean i know all the answers? yay!
