In this free step-by-step crochet stitch tutorial I show how to make the spiked stacked triangles stitch. This stitch is a solid crochet stitch that has a nice texture. It creates dense, durable fabric and works great for potholders, washcloths, decorative pillow covers, laptop sleeves, bags, scarves and other projects that need warmth, structure, and durability.
This crochet stitch tutorial includes detailed photo instructions. The spiked stacked triangles stitch is a four-row repeat. For this crochet stitch you should know how to make single crochet. The tutorial below shows how to make a spike stitch (or a single crochet spike stitch).

Materials and tools
Yarn: For this tutorial I use Hjertegarn DIAMOND mercerized cotton 8/4, 50 g = 165 m, color: 706 (sea green). However, you can use your favorite yarn depending on the crochet project.
Hook: I use a 2.0 mm hook. If you are using a different yarn, choose the hook size that is recommended on your yarn label.
