I know nothing about this topic as such but being interested in trying circular needles and using more than two needles I was reading a section of tips and there was a comment about a 'ladder' being created as you work between the needles and the comment was that people often need to additionally 'tighten' the yard at this section otherwise you naturally create that ladder.
Is there transferability to this issue you've talking about and it could be that for that stitch you need to tighten or even change needle size (if you can't eliminate the problem)?? I've never made socks so I'm just throwing the idea into the pool.
Is the hole at the top of the gusset? Maybe it's where you slipped the first stitch? I wonder if you knit that first one normally then slipped the rest it would be tighter at that point.. :thinking:
You know, Jan....I think that it's the slipped stitch at the start of the row when I'm working on the heel. You know, the part where you go back and forth on the heel? I think I'm just going to do a purl or knit for that first stitch from now on. Maybe that will fix my one hole problem.
