I also do rag rugs but I knit them while watching TV . I use size 12 needles and make different sizes. I knitted a rug for the bathroom to hug the toilet. Knit a square then knit ### of stitches , put the rest on another needle to save. knit sts.as long as you want. end. Bind off ## of sts. for front of toilet and knit remaing sts to match other side. This rug will be in a U shape.
