Sorry, Myron, I anticipated you were just starting out. My outburst about colour, MacLaren, etc. was inappropriate.
I guess my teachering (film) hasn't gone on holiday.
If I'd been hip, I'd have put, "Just in case you don't already know, here's some other info."
Two more things: (just in case)
You can buy unexposed B&W PRINT stock cheap (Kodak used to make 7302 and 7362. both equally suitable. Maybe Kodak's still is making them.
and submerge it in photo fixer as step #1. This will clear the film of light sensitive emulsion, leaving the gelatine intact.
Use a "non'hardening" fixer for this.
Advantage: fixing with a non-hardening fixer (without a developer step), allows the gelatine to remain very porus and receptive
to dye. The labs use a hardening fixer as it toughens the gelatine for sturdy projection, but for you it makes any dye absorption take more time.
Print stock film base is transparent. Camera stocks' base is grey.
Done.

Pretend you see no spelling errors; I can't tell the difference, and Safari has no spell check.
