Your question: How do you block an acrylic yarn sweater?

As a general rule, steam blocking is the best way to block acrylic items and squares to specific measurements. To block, use T-pins or knit blockers to pin down the project to a foam mat. Then, use a steam iron and hover it a few inches away from the project, and let it rest overnight.
