With double knitting yarn (I think in the US that's Sports) and my needles are 4mm. Start with 1 stitch. Next row increase into that stitch then knit those 2 stitches. Turn. Increase into first stitch and knit across the row. Keep increasing one stitch at the beginning of each row until you have 60 stitches on your needle.
Knit 1, slip 1, k1 and pass slip stitch over (psso). Continue knitting till the end of the row. Turn and repeat until you are down to 1 stitch again. Cast off.
See? Easy Peasy as the kids say (or used to).
I can't say I'll post a pic of the finished rug yet as I'm not sure if the warm weather will turn up before I've got enough squares done (I don't knit much in the summer). But here's hoping that at least by the end of next winter I'll be able to show the finished product.
Have a blessed day!
