I don't think there is any one specific way to go on carpet. If your not a purist, then anything goes.

The carpet sold at upholstery shops for cars usually has a rubber/flexible backing to make it easy to install and conform to shapes. But it can come apart much quicker than house carpeting under normal use; especially where your heels rest. Carpet pads can be used as a sacrificial carpet to eliminate that problem.

Use artificial fabrics to stand up to rain and color fading. Wool is probably a bad idea.

Cut loop is traditional. If you want to be different, then use loop pile.

I put mine in without and hems that are traditional on Cobra carpeting. I like the one-piece look.

I put a felt underlayment down first and glued it lightly using spray contact cement.
