Because apparently if you have too many things going at once, you don't finish as fast and your gauge is apt to change.
And then you get this problem...
Those are my socks. I didn't think it could happen, but it seems that my knitting has gotten even looser. Note where the toe decreases start on the finished sock. And then note that I've just started the toe decreases on the unfinished one. I think we have a problem.
What do I do? I'm drawn to the idea of frogging to the heel, then re-doing the foot. But do I try to knit tighter? Or do I hope and pray that I brought my 1.5mm DPNs? Yes, I do knit socks on 1.75mm DPNs. I'm a ridiculously loose knitter. And by that I mean that I knit loosely. ;)
