Hi Maria--as you can see my user name is Marria, which was my nickname when I was a kid. My name is actually Mary.
Anyways---yes, I do crochet and knit both. I learned to crochet then I learned to knit. I enjoy both, and although I know some people think one or the other is harder, I don't find that to be true for me. I just think they're different.
I like to use crochet for afghans and sometimes scarves, and knitting for garments, although I have a couple of crochet sweaters on my Ravelry queue, and eventually I'll make one. I also sometimes put crochet edgings on my knitting.
