I don’t know whether it is true for all knitters but in my experience, whenever I take a WiP photo of my knitting I spot a glaring error way back in my work [i]that was never there before[/i]!
This is my [url=http://ravel.me/plumbum/q1tnx]Windswept Shawl[/url], at the end of Chart 6 and with a new lifeline in. Charts 7 and 8 remain before edging. There is a long way to go but it is already too large to spread out on the needles for display. It will now remain a blob until finished and no further errors will show up until I block it. They always appear then, too.
No – I shall not be pulling it back to fix the problem.
