This pattern is mostly knit with just garter stitch and some stacked decreases and increases added in some places. Some familiarity with stacked stitches technique is desirable, but not required. Despite its visual complexity, this pattern is fairly simple. There are no long stacked increases or decreases. The same structural elements repeated on top of each other create tessellated fractals that look like icicles or stalactites. The PDF has instructions for three different stripes in the PDF: two stacked ones (tall and short), and one zigzag. You can arrange those any way you want. There is also a description of a zigzag edge with sharper “teeth”. I think it is decorative on it’s own and goes well with this kind of pattern. I personally think that short-tall-short stripe sequence makes a rich-looking border for anything from wraps to sweaters, and does not need to be complicated with anything else. You can start with it, and then see how you want to continue.
