knitting with several strands isn't hard, just can get a little twisty. and you have to pay attention to get all 4 strands as you go back across your stitches. but it makes things go really fast! check the general forum for lots of comments about the homespun yarn... the huge needles take some getting used to. personally I don't like them, but to each their own! try it! what's the worst that can happen: you don't like it and you frog it.
you can do it!
