Waveform is a textured knit using twisted stitches to create undulating waves of texture. The stitches are simple knit and purl, some into the back loop and a 2 stitch cable which can be done without a cable needle if you like.
You need 200g of any sock weight yarn. I strongly advise a solid or subtle semi solid for this pattern, or perhaps an ombre... as highly variegated yarns might conceal the textured pattern.
The size in the pattern is knit with ~190g of sock weight yarn but it could easily be made in a heavier weight and you can easily adjust the size bigger or smaller by simply changing the number of repeats knitted.
