Big Skein of Sky Blue 3/4mm Silky Vintage Rayon Thread - Crochet, Embroidery, Textile Art Etc

I found a big brown paper package tied up with string (see last picture) in one of the warehouses I cleared  full of skeins of this lovely shimmery summer sky blue
rayon thread.
It's 3/4mm wide, exceptionally silky and each twisted thread is made 
up of 2 thinner twisted threads (also made up of thinner threads !)
Wonderful for crochet, embroidery, knitting, tatting, braid making, jewellery cord,
textile art etc
I don't know what length the skein is but there's a lot of thread here
- it weighs 55g (if that helps !)
