Upholstering with velvets?

Hello everyone, I'm a little bit curious about whether there's any special methods you have to use when using silk velvet to reupholster arm chairs and couches as i've been wanting to give it a shot some time in the future and want to have at least most of my facts straight before i start.

something in the realm of these sorts of styles

Is there any sort of underlay you have to use? or any particular wadding? and can you just use tacks and staples the same as you would with regular fabrics?
