Bit of an old thread but rather than start a new one...I have recently undertaken fish skin leather making as a project so I thought I'd share what I found out. My first attempt was with three foot Salmon leviathans!
Glad you liked it, I decided to take copious pictures so that I have a future reference guide and if it's helps anyone else then all's good. You can see diamond shapes of brown coloured light if you hold it up but perhaps they scraped it a little thinner and I'd guess they didn't bark tan?Thank you very much for stopping so often to take progress pictures.
If there was no easy ice, I've been told over and over that Inuit used fish skin for light windows replacing a snow block in an Igloolik (snow house).
Otherwise pretty dark but for the light from the kudlik.
Question = How transparent is your finished fish leather?
