Thanks Sharly: I love this site - and the advice is invaluable. I'm now attempting a jumper for my niece and of course the curling issue, as with the sweater, is plaguing me. I woke up one morning thinking about it and decided I needed professional help, so I came right to this site. It's nice to know there are so many talented knitters out there that are generous enough to help beginners like me.
Thanks for the advice. I'll try steam only without applying the iron to the stitches. And you're right: my knitting can also be tight, so I've been careful to check the gauge every few rows keeping it in line with my swatch. I never thought a gauge swatch would be so vital to a finished project, but I'm learning. Thanks again for the advice.
