Slip Slip Purl (SSP) /
Slip Slip Purl Through the Back Loop (SSP tbl)

The SSP stitch is a left-slanting decrease that mirrors the P2tog and is worked with the purl stitch. SSP tbl is a right slanting decrease stitch that mirrors the P2tog tbl and is worked with the P tbl stitch. To do an SSP or SSP tbl on the loom, 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.

This stitch is more common in needle knitting since loom knitting is all done on the RS.


SSP
SSP tbl
Because SSP is a left slanting decrease, it is worked on the right side of the loom in flat knitting. If you need to decrease on the left side of the loom, use an P2tog stitch. The following directions assume you already know how to do the purl stitch.
  1. Pick up one loop and hold it on your knitting tool.

  2. Take the wrap off of the peg to the left and put it on the empty peg to the right.

  3. Put the wrap on your knitting tool back on the peg on top of the moved wrap.

  4. Purl the stitch using the two wraps on the peg as you would if it were one.
