The first of my addictive down-the-rabbit-hole double-knit blankets was the Sunburst. It had a nice straight-forward design that was easily described by means of a construction diagram and a conventional chart.
This was all that was needed to describe and portray this simple pattern. But, if you look at the blanket closely, you may be able to see the smooth sides of each of the 1/8th sections of the blanket are smooth, not serrated as they appear in the chart on the right. The central double increase pushes the stitches out, thus causing the actual continuous edge stitch columns to fan out, but on this kind of chart without using thousands of No Stitch symbols, this is the result. Below is a sketch of a tiny bit of such a chart with the outside columns running smoothly.
Before the advent of the truly amazing Stitch-Maps, this charting problem hobbled my ability to properly portray more complex designs: if you want to knit the pattern, surely you ought to be able to read it!
