Learning to fix a mistake in your knitting is really empowering. I remember in my early knitting days I would traipse down the hill to the local yarn shop whenever something went amiss in my knitting. The owner, Tina, was really patient with me, and picked up dropped stitches, helped me to rip back, and eventually, once my confidence had grown, she showed me how to fix my own mistakes. It really marks a change in your relationship with your knitting when you are able to get a project back on track on your own.
