I found this today while trying to test a swatch.
This covers cotton, silk, wool, linen as well as blends & man-made fibers.
It's much easier for me when things are in chart form instead of paragraphs so this is now printed & tacked up in my sewing room. I found it quite handy!
Hope it can help someone else.
