that knee is looking a bit unstable . s <| sep |> I ' ve never had a problem with suggested weightneedle sizegauge but I think that ' s because I knit almost exactly to the average or correct I suppose tension , so the suggested needle size on the label is always accurate for me i . e . if it says 4 5 . 5 mm I will knit it with 4 . 5 or 5 mm needles . I ' m also super picky about the fabric having the right about of drapestretchdensity so used to swatch all the time before I realised my gauge is almost always exactly what it ' s supposed to be , so now I only swatch if it ' s for a close fit garment . I ' ve only found one yarn that is obviously not the correct labelled weight , but I knew that before buying online as it was the # 1 most often commented thing on Ravelry about that yarn .
