I'll need to make about 100 prints, but the negative hasn't been made yet. Hopefully dodging & burning won't be required, but you never know.
Based on the advice here, I will probably have a single negative in the carrier, and expose 4 prints onto each 8x10" using a black card mask. Should be reasonably easy to expose 25 sheets sequentially and put the paper into a paper-safe. Obviously I will make some tests first!
Thanks for the advice, everyone
