Decreases 2
These are additions (click for bigger version) based on comments on the previous entry. A few of them could be possible replacements as well.
I forgot about k2togtbl (also written as k2tog-tbl) as a paired decrease to k2tog.
I'm happy to learn about sppo, because I don't think I've used it before. (It also goes to show you I haven't explored as much knitting technique as I wish I did! Call this a learning experience...)
The last 4 are concessions toward the various decreases using more than 2 or 3 stitches, in the regular fashion and twisted through the back loop. There aren't any charts, because the designer makes up their own. You see the introduction of the double-line, which I don't particularly fancy, but it comes as a necessary evil: this chart must be legible from at least 5 feet away.
