Blocking your crochet items truly enhances, beautifies and puts the finishing touch on your crochet projects. It is is an important step toward making your crochet pieces look more professional and a very effective way to even out tension, especially for open work, to really show off the pattern or shape your finished work to achieve a balanced symmetry. Commonly, blocking is used to help flatten areas where work has curled, enrich the look of lace or textured stitches and highlight stitch delineation.
The answer is No
. It really depends on what it is and what it is going to be used for. For
instance, items like amigurumi, booties or baskets do not need blocking, when items like blankets,
dollies, snowflakes, etc. would look much better after blocking. I personally always choose to block
my blankets. The end result looks more professional with straight edges, neat stitches and free from
creased and curled areas (see images below).
If you are not sure which method to follow, check your yarn label and do some research online. You can also block a smaller swatch as a test. It is better to try and fail on a swatch than on your entire blanket.
