Help Make the cloth thicker?

[richardmuthwill]

I'm working on a project where we need to be able to drag a cloth and I obviously went for Obi.

I need the cloth to look like a thick duvet cover, more than a 1mm thick piece of cloth - any tips for how to do this?

Ideas so far:
- Shader on the 2D cloth to give it depth / make it look thicker
- 3D model and obi volume

Any other ideas or any idea how I could use any of the above ideas to acomplish this?
