From the Stitch Description: Here is a handsome little texture pattern that is really a six-row development of Double Seed Stitch. The “little pyramids” are wide, short triangles of knit and purl stitches. If the odd-numbered rows are used on the right side, then the knit triangles will point upward and the purl triangles will purl downward (Knit Pyramid). If the odd-numbered rows are used on the wrong side, then the effect is reversed (Purl Pyramid). The forward-and-backward alternation of the same three rows to form the pattern is interesting. The fabric is flat, firm, and shapely, requiring little or no blocking.
