K2tog & SSK and K2tog tbl & SSK tbl

On the knitting board, the k2tog and ssk (or k2tog tbl and ssk tbl) are paired together, one being done on the bottom rake and the other on the top or vice versa. This is done to ensure that the slant of the decrease is correct on each side of the fabric. A description and direction for each decrease is given below. The easiest way to set up the knitting board is to setup the stitches on the bottom rake and then turn the board and set it up the same way. So, work a K2tog stitch on the left bottom rake and a SSK stitch on the right bottom rake, turn the board and repeat. If you are using k tbl stitches, work a SSK tbl stitch on the left bottom rake and a K2tog tbl stitch on the right bottom rake, turn the board and repeat.

K2tog is a right slanting decrease stitch is worked with the knit stitch. K2tog tbl is a left slanting decrease stitch worked with the knit tbl (e-wrap) stitch. To work an K2tog or K2tog tbl stitch on the loom, you will need to pick up one wrap, put it on the peg on either side (depending on the stitch), wrap the peg as called for and then knitting off. You may see them combined with yarn over (picking up the stitch from where the yarn over would be) or near the ends of the row to decrease.

Slip Slip Knit (SSK) /
Slip Slip Knit Through the Back Loop (SSK tbl)

The SSK stitch is a left-slanting decrease that mirrors the K2tog and is worked with the knit stitch or flat stitch. SSK tbl is a right slanting decrease stitch that mirrors the K2tog tbl and is worked with the K tbl (e-wrap) stitch. To do an SSK or SSK tbl on the knitting board, you will need to pick up one wrap and hold it with your knitting tool, move the wrap from the peg on either side (depending on which stitch) to the empty peg and the replace the wrap being held on the knitting tool back onto the peg.
