One of my favorite stitches is the box stitch. It’s a variation of the shell stitch but with a dramatically different result. In my experience, it’s used best with a shiny, smooth yarn that shows it’s definition most effectively. For baby afghans, I like to use acrylic yarns for the ease of care (machine washable) and Caron Simply Soft has been my favorite.
Crochet Cabana has the best tutorial (with pictures!) on both straight row and diagonal row box stitch. Visit them here: http://www.crochetcabana.com/stitches/box-st-in-rows.htm Don’t be intimidated by the instructions. It’s really a quite simple stitch.
If you’re inspired by this post, I’d love to see pictures of your project using this versatile stitch.
