I was shown how to knit as a young gal and always found it difficult.
Me too. But if you have conquered crochet, your hands already know the important parts like tension and holding the yarn. And we are so much more patient in this phase of life than when we were 'young'. lol. We understand learning takes time and you won't instantly be good. If you still want, a few hours with YouTube could teach you what you need to know. My mother is a long time crocheter for the same reason, she couldn't get the hang of knitting when young. Now she wishes she could knit so she could make socks. I'm encouraging her to try as well.
@Macknit that sweater is going to be amazing!
