Hello Val and all in the list from Brno,

this autumn I started to teach SignWriting at university, and I haven't found anywhere on the web, nor in Stefan's book photos of facial expressions.
Some expressions are not easy to imagine. There are some pictures in Cross-linguistic guide but mostly pictures of mouth pattern but not eyebrows.
Are there exact picture of meaning all symbols of eyebrows in SignWriting?

Thank you
Honza, CZ
