Hi Alice,

Welcome and good luck with this project!

My advice would be simple... Since you want to make this a personal project, mix your own "emulsion" for the print instead of buying "Liquid Light" or the equivalent (because that will work but you may feel less achievement from using "premade" formula).

Also, since this is likely to be less sensitive to light than enlarging paper, plan to use the largest format negative you are comfortable handling, you will probably be making a contact print.
