Iceberg, as with many of my stitch patterns, starts by turning the letters of a word into numbers, charting the numbers, and then turning the chart into a knitting pattern. Here is my blog post about it.
While it can be worked as an all over pattern, I think it's at its best worked as a panel with purl stitches at each side.
This is one of many patterns funded by my backers on Patreon.
Shown with a cast-on count of 56 stitches.
