Hmm, I found this: https://www.sewingmachinefun.com/doll-clothes-fabric-types/

The main advice I would personally give is to buy fabric in-person, so you can get a good sense of how it looks and how it lays. Maybe even bring a doll with you to drape it on to see how it looks.

Is there a list anywhere for fabrics to use on doll scale? I know the way fabric lay and the thickness of it can be very different on a smaller scale so I was wondering if there was a resource that goes into detail with this.
