So, does this mean to k10, move your marker to other needle, slip two st to the other needle without doing anything with them, put your LH needle through into the two st you took off, and K them together so you now have ONE st on the needle?
Correct. The SSK decrease slants the opposite direction from the k2tog.
And you can knit inside out/outside in whichever you want. If the decreases make the circumference too small, you may want to flip it around so you're knitting on the outside. Whichever way you're most comfortable.
