A double knit cowl in progress.
Compare the textures of the backgrounds on either side of this fabric. The red yarn has a slightly bigger gauge that the white yarn, with the result that it mounds between the shapes. The disparity is held in check by making the colour changes by threading the stitches from the back layer to the front. I could have effectively subdued it by working fewer rounds of the red yarn, but I like the cushiony effect. The majority of the rectangles are worked in reverse stocking stitch, but occasionally (lower left bottom picture) I’ve used stocking stitch for variety!
