settings for fabric

I’m not sure how to setup fabric in the nodes with blender. I have an image and its normal. But I don’t know how to create translucency and perhaps use a falloff curve on the edges. Any help would be greatly appreciated.

OK, I have the translucency and 2 sided-material worked out, but I could use some help on a fall-off curve. Any ideas?

You can check this file for a falloff example, hope this helps.

Thank you, that helps a bunch!
