Socks and striped ones.

For some time now I have been looking at these socks and wanted to make a pair. Now I finally working on them, but finding a problem. Where the coloured yarn and the solid yarn switch places, a ridge apears on the inside of the sock and I hope I will not feel it when I’m wearing them. Love the effect though.

Yarn: Opal (Black) and ONline Supersocke 4-fach Neon Color
Needles: KnitPro Zing 4.00mm
