Slipped (or skipped) stitch patterns are created by slipping or skipping
individual needles. The slipped needles do not form stitches and the
working yarn strand is carried UNDER the needles (as opposed to
Tuck, where the working yarn is carried OVER the needles).

Punchcards
Because multiple needles can be slipped, a variety of punchcards can be used.
As an LK-150 knitter, you will need to "translate" the black and white holes in punchards for your machine. We will cover this in a following lesson.
HINTFor Slip, needles in "B" (working position) DO NOT Knit. Needles in "C" or "D" knit. (this differs from tuck). So the logic for hand selecting needles is different for slip than tuck.
