I just joined this KAL today, which was coincidentally 24 hours after starting my first toe-up socks (on 2 circs for the first time). I am certainly enjoying being able to slide the sock on without battling with double points.
No pattern planned yet. I'll probably just choose something simple from Sensational Knitted Socks this time around.
Have fun everyone! Here's a picture of my Halloween-themed socks.
