Bingo, thank you!!

They have about 200 different colours, and a swatch book with rough
transmission curves (more detailed ones may be online).
Sold in sheets of 1.2m x 1m or so, for $23 ea.
Doubling layers to increase attentuation would be much easier than
halving...

Looks like I'll have a few leftovers to share. You can see it next
month.

Ease of choice and specs make this look like the better option - plan B
is still trawling craft shops.

Thanks again,

Volker
