Proper blocking of a knit garment or accessory can go a long way toward making it look and fit better, and it can help restore symmetrical balance to a misshapen afghan or rug. Blocking sets the stitches and can even enhance the drape of the fabric.

What is the point of blocking knitting?

Blocking is a method of stretching and shaping a finished knitted piece to reach the dimensions suggested in the pattern, to make two pieces that need to match the same size, or to make your stitches look nicer and more even.

Is it necessary to block a knitted sweater?

If your garment is going to be pieced together, you should block the pieces before sewing them up. This will help you to line up seams and to even out the garment to make the joining easier. After subsequent wearing of the sweater, wash the garment as the yarn label indicates.
