I’m new to knitting and am working on a prayer shawl. The pattern says to cast on 63 (or multiples of 3)…the entire pattern is then K3, P3 knitting the purl stitches and purl the knit stitches. I start and have 63 stitches on my needle. I turn the needles and K3, P3 to the end and count my stitches…still fine. Eventually, even though I come out with a multiple of 3, I’ve gained a stitch somewhere. It’s not the infamous extra stitch explained in the forum. I always make sure the thread is coming off the needles correctly but somehow gain an extra stitch somewhere. Does anyone understand and can offer some advice??
