Use SSP2tog tbl and SPP

If you need something that looks like an SSK, use SSPtog tbl.

Slip 1 kwise twice,

return to the left needle,

purl tog tbl (insert right needle into back loop of the second stitch on the left needle from left to right, and then through first stitch on the left needle; purl).

It is complicated, but usually you aren't decreasing across an entire row on the purl side, so I chose it for it's look on the right side of the work.

Need something to look like K2tog? SPP!

Slip 1 purlwise,

Purl the next stitch,

Pass the slipped stitch over.

I got these mixed up 20 times just writing these two posts, but I think the finished line of decreases is worth it.
