Injured, and lying on the ground

I cast on Snowdrift last night, and have got past the armhole shaping of the back already. Hopes are high. However, I really like how surface is turning out, so I have promised myself (and we all know how well *those* promises work out) that I will complete a piece of surface for each piece of Snowdrift.

However, Snowdrift is growing really fast (see above) and I’ve already got 3 pieces of surface done (only back & 2 sleeves to go, there), so it wouldn’t really hurt to do 2:1… would it?? The back on Surface will take a lot longer as it’s only DK instead of chunky. I could alternate evenings/sessions instead. Can you see the cracks appearing already!!
