Increases

Here's a bigger version.

BASIC INCREASES

YO and yoX (X being any number of stitches; see the symbol as well) cover any number of stitches made by winding yarn around the right needle, and cover both knit and purl yarn overs.

Kfb and pfb don't have a specific symbol assigned, but I've seen them in some cases as a 2 above a V. This pair is also known as bar increases, for creating a slight bar at the bottom of the originating stitch.

INTERMEDIATE INCREASES

M1 stands alone, but really it it's M1L, if you're considering matching increases. So for now I'll leave it as M1, and have M1L and M1R. Unless someone has any insight on this. 

LRI and RRI, the raised increases, involve knitting or purling into the stitch to be worked, or just worked. This is my personal favorite increase, and works well with top-down sweaters.

In this file, LRI and RRI are advanced decreases, but I think they're intermediate. It'll be fixed in the final table.

LASTLY

We have the generic incX, which could involve multiple yarn overs or M1s or 4 needles and a glass of wine.

Does anyone have other increases, the esoteric, the strange? (Also on Flickr.)
