I finally finished my bathroom rug. I started last Fall on a coiled version, ripped it out twice and found this stitch to use instead. I actually finished it last weekend then noticed that about one-third of the way into it, I wasn't paying attention and my slipped stiches were done with the yarn in front instead of the back. So, I dropped the stitches in each column, re-knitted them and on my last column ran into a problem where I had already woven in some ends and ended up with a big hole in the rug. So I ripped out about one-third of it and redid it. Now it's finally done and I can stop putting down towels on my cold floor.
I did this with Lion Brand Wool Ease Worsted, double stranded (it was leftover from a cable sampler afghan I did years ago that was my first big project). The stitch is called 'Triple L Tweed' in Barbara Walker's Treasury of Knitting Patterns (the blue one) and is usually done in 3 colors. After I made a swatch I realized there could be a diagonal pattern if I alternated between 2 colors every two rows. I had to make an Excel spreadsheet to coordinate the color changes and pattern changes in the rows. But it's finally done and I'm enjoying a glass of wine and will enjoy having warmth under my feet from now on in my bathroom. Finished size is about 45x30.
Update: I've added a PDF of the pattern below if anyone is interested.
