Someone asked me what Stroud was. It is a really really dense wool broadcloth. It is not thick like duffle; it is about the same as melton - but the fibres are much more densely intertwined. It is warmer than both melton and duffle. Usually comes in a cream off white - although some native groups in the US dyed it red or blue. It is used for parka linings (if you can get it and can afford it); mukluks, mittens, etc. Not that you will be able to distinguish it very well in my photos - but the cream/white fabric is Stroud. The black fabric in the mukluk is melton.
Hope that helps? I won't be posting for a few weeks as I have to go out of town rather unexpectedly. Later.
