Recently, while designing a shawl, I realized that I needed a way to do a knit side oriented double decrease but from the purl side (the stitch is worked on the purl side, but the double decrease shows up on the knit side). Happily, I found a blog with a fairly simple explanation (plus a great photo tutorial) of how to do this. Yay!
For many knitters, this might be the end of it, but it got me to wondering. How would a knitter do a double decrease that was purl side oriented?
While fleegle's trick is super cool, on the purl side it look like an elaborate right leaning decrease. I (and possibly you) want to be able to make a double decrease that is centered on the purl side. But, alas, google was not helpful. A search yielded no useful results (if I missed a tutorial for this, please let me know.)
The knitting nerd in me (and that's a large part of me) insisted that I figure it out.
It turns out to be fairly simple to do. All you need to do is: p2tog, s1, psso.
I found slipping the stitch over on the right needle to be a bit tricky, so I moved the the stitches onto the left needle for slipping. The less tricky (for me at least) way is what I've included in the photo tutorial below.
PSO-CDD (in 4 easy-ish steps):
1) Purl two together.
2) Move stitch from right needle to left needle.
3) Pass slipped stitch over.
4) Move stitch back onto right needle.

Knit side view:
So simple, yet so complex looking (as is much of knitting). I hope this has helped you in your search to become a more nerdy knitter.
Just me, huh?
P.S. I was pretty excited about my status as a nerdy knitter when I figured this out (even though I'm pretty sure that I'm not the only one who has). So I texted TK and told her that I'd figured out how to do a purl side oriented centered double decrease. A short time later I got a text in return that said, "Is it p2tog, s1, psso?" Yep, ego deflated. Tell me again why I hang out with such smart knitters?
