can you block acrylic yarn?

Carefully pin out to shape, then put iron onto steam, hold about 1-2 inches above project and allow steam to penatrate for approximately 10 seconds at a time, while gently patting with finger tips any irregularities in the knitting to even out. Do this all over project until you have covered it all.
