Total newbie needs help! I'm working on a basket weave stitch, and the next row I was supposed to be doing was an all-knit stitch (to separate in between each set of knit/purl rows), but I accidentally started purling instead. After doing 3 purls, I started to try and go backwards, but I got stuck and now I don't know what I'm doing. Can I just unravel those other 2 purls without ruining my knitting? What should I do?!
