Thank you JRJ for the additional Venetian Bead Pics!
Found that Blogger Alain R. Truong had done a beautiful job of compiling Photos and other info about Fortuny Clothing and there are some 8 pages of photos- some with close ups of the Venetian Beads.
I have a translate feature that pops upon my Mac as some of it is in French, but if you do not, the photos speak for themselves.

There are many things written about Fortuny and his Wife as they were quite the creative team and very ahead of their time. They brought Women's "Tea Gowns", formerly a very stiff affair, and Formal Dresses for Social Occasions into the Modern Era just at a time when Women were breaking out of the old Social and Political Norms. This You Tube is kinda long but gives a nice overview for anyone interested:

The youtube video you referenced was great as was (in its way) the subsequent youtube video showing Anna Chancellor's visit to the Fortuny factory. I had no idea Fortuny was a painter and innovator in theatrical lighting. After seeing the second video, I found that the firm has a website, Fortuny.com. No printed velvets or pleated silk, but make other fabrics, lamps and furniture.
