There aren't any "written" line-by-line instructions that replace the charts for Sylvi.
True enough, those charts and all the many many symbols are daunting. My suggestion is: color code EACH SYMBOL in the chart KEY....then color code all the symbols in the chart to match the KEY. It's the only way I could visually sort out each row. None of directions behind each symbol is difficult. What's tricky is following along accurately.
There is an ongoing KAL in the Groups over at Ravelry. That KAL is still active.
Be aware, the pattern is under strict copyright protection, so other knitters who might want to help you won't be able to give you explicit written directions based on the chart directions.
The only thing I did to change how I.followed the charts is that I made all my bobbles separately and sewed them onto the coat. I knit some of my flower petals separately, too.
