A knitting gauge is a small ruler with a slide used for measuring gauge in stitches per inch. Knowing stitches per inch helps knitters create garments to desired dimensions.
A cable needle is a single, double-pointed needle used to hold stitches in front or back of the work while twisting a cable. These needles may be straight or curved.
Illusion knitting is created with knit and purl stitches in two colors following a chart. The knitting looks like a solid pattern when viewed head-on, but when viewed at an angle, a picture emerges.
Seed stitch is a textured pattern created by alternating knit and purl stitches (knit 1, purl 1) over an odd number of stitches so that knits and purls create alternating bumps (seeds) in an alloever pattern.
Duplicate stitch is embroidery worked on top of knitted fabric using yarn to copy knit stitches and cover them with a different color. The resulting pattern looks like it was knitted into the fabric.
English knitting is done with the yarn held in the dominant hand. The dominant hand begins a new stitch and throws the yarn over the needle. English knitting tends to be slower than continental knitting.
A cable is a raised pattern that crates a braided look on the knit fabric. Cables are created by placing some stitches on a holder and knitting them out of order, crossing some stitches in back or front of the work.
A dropped stitch is usually a mistake in knitting, as a stitch falls off the needle and creates a ladder (run) as it drops down the rows. Sometimes, however, stitches are dropped deliberately to create a lace pattern.
