Yarn substitution

Does anyone have a good substitution for Berrocco Smart Cotton? It looks like a DK weight. I checked yarndex but couldn’t find anything. the pattern is the Vanessa Cardigan - it’s lace so it would need to be blocked right?

How about this?

That’s pretty - thanks! I was a little confused about what blend to get, or if I should get 100% cotton. I need this for a late March bday, so I need to get strted soon. Thanks!

This is the pattern - http://www.berroco.com/181/181_vanessa.html
I was also wondering if I could do it in a light mohair yarn - or would that be too heavy now that we’re getting (hopefully!) into spring and summer?

There’s always Svale…they advertise it as a three-season yarn…
