The Single Crochet Thermal Stitch creates a solid, dense and very warm textured fabric. It would be a great choice for warm blankets, heavy sweaters, and mittens!
The Crossed Double Crochet Stitch is worked to create a crossed-over effect on your work. This technique is generally used as part of more complicated crochet stitches. By itself, it creates a solid fabric with distinct diagonal and horizontal lines.
The Star Stitch creates a thick fabric with very little drape. It would be a great choice for more structured items like coats, baskets, purses and hats.
