I *LOVE* sweaters and would love to learn to knit well enough that I could make myself something eventually. I really love intarsia sweaters, but I don't think I'll ever be able to do anything like that. Right now, even my scarf stitches aren't consistent.
I wish you luck in switching your style. If I've tried to learn something new like that, I tend to talk myself through it. Then when I'm doing it I can hear the instructions in my head. Eventually I get so I don't need to do that.
I crochet some, but mainly afghans. I can handle one needle at a time. When I try to knit, my projects always seem to go to hell in a handbasket. I have an old Brother knitting machine which has cards for intarsia. I bought it off Ebay, but some of the needles seem to be slightly bent or misaligned. I couldn't knit anything more than a few rows before it resulted in tangles and broken yarn. It came with extra needles but I have to find someone who knows how to realign and replace them on an older machine. Maybe I'll put that request for repair on my xmas list for next year!
