The ribbed collar from the pattern ended up way to high for me, so I decided to replace the ribbing by an applied icord edge. It was my first time making an such an edge and I was just wondering whether it's just inherent to this edge that it stands up, or that I should decrease a bit before the icord (I already went down 0.5 mm in needle size). Also, especially when laying flat the edge tends to fold over so that the floats are almost visible. Hence I'm worried that after a while that will also happen after a bit of wear
