I've never seen Kureyon do that before, but I've only done a hat and a vest with it, both two big to get that effect. I have to try wrist warmers with it now, just to see.
Sorry, Kat, but hte quick answer to the Noro question would be...yes.
I just finished mitts, they kinda match if you hold one upside down beside the other and squint really hard.
The colours are great though!
Were there any knots in your skein? Noro's not so good about maintaining color progression or dyelot with knots...
