Absolutely! It’s the icing on the cake—it gives the piece its final shape and texture. In my first photo, the knit was simply stretched (Method 2 in the attached document). In the second photo, it was steam-blocked (Method 4 in the attached document). Which one do you prefer? Whether using a crochet hook, a knitting needle, or a CMK tool, you will achieve a beautiful, well-positioned knit.
