Blocking Wool/Acrylic blends

[turtledove]

Hello Everybody!

I have a question.

I´m knitting a sweater with LB Wool-Ease, which is 20% wool, 80% acrylic. I was wondering if acrylic/wool blends can be blocked. If they can, what exactly is going to happen to my sweater, will it get bigger? smaller?

I wouldn´t block it if I didn´t think it needed it, but it´s looking very wrinkled.

And, besides I think it´s about time I blocked something.

Thanks!
