Okay, so this is taking some calculation. I have 78 sts on the sock currently (40 instep, 38 heel). Since 78 is not a multiple of 4, I'm guessing that I need to do the first round as a 2 st decrease instead of a 4 st decrease. Do I decrease on the instep or the sole side?
I'm also concerned that somehow my calculations are going to be wrong and this isn't going to fit. I should probably run a lifeline in case I have to frog back to 78, just for some insurance.
In other sock news, this entrelac sock class requires 6 colors! Wow... that's a lot of color. I think I'm going to do an autumnal design: red, yellow, brown, green, orange, maybe deep purple...
Well, back to work.
