So, knit side A of sock 1, then side A of sock 2 (don't forget to drop working yarn of sock 1 before moving to sock 2). When you finish side A, adjust your needle tips so you can knit side B. Knit side B of sock 2, then side B of sock 1 (remembering to change working yarns in between. You will keep working around like that, doing whatever increases your pattern says to get the shaped toe you want. The toes, side by side, should look something like this:
