[Frameworks] Homemade fixer?

[Scott Dorsey]

You really need fixer, but because the chemistry is pretty much the same
all over, the fixer used for kodaliths at the print shop or the t-shirt
shop will work... so will the fixer used for x-rays at the hospital. 

You can just make sodium thiosulfate or ammonium thiosulfate solution 
without a hardener... it is asking for emulsion damage to do that, but it
is better than nothing.

The salt solution... sort of works.... it will work for a little while, but
it won't work very well and you will need to refix your film as soon as 
possible with a proper fixer.  

Find a still photographer in your area who might have some idea of 
old leftover supplies and older photographers.
