Material Choice ?

[sandman]

I'm a bit new here and during my wanderings thru the various messages and threads I have passed by a Material & Properties chart. I can't find it again does anyone know where is it hidden, the search function isn't helping?
The chart listed the various materials, common weights and the material properties.
Listed qualities were the ability to hold a pleat/crease was pilling an issue with the fabric etc.
As a first timer this forum has lots of great information but it is a bit overwhelming to get all the various choices sorted out.
Thanks
