I think every single one of my friends and I ended up with extra stitches on our needles every 5-10 rows on our first few scarves. We just counted every couple of rows, and instead of going to the trouble of ripping out a couple of rows each time, we would just decrease by knitting two of the stitches together. It looks fine, and anyways, my mottos is "mistakes are punk rock!"Beginner knitter here and that happened to me too. Like Aurelia & DeadDisco, I also combined two stitches.
I finished the knitting on my garter stitch scarf today (YAY!!) and will weave in all the ends tomorrow. I made my mine just red and white for the Cat
in the Hat
Knitting the scarf was fun
If you have 19 stitches instead of 20, can you "divide" a stitch in half to get the 20??
