Rc takes much longer to stain and you might encounter messed up color splotched edges so leave some room for trimming.

Tea and coffee should be really brewed strong for this and let it cool unless you want to mess up the emulsion. You may have to weigh the print down as they can float and you get uneven staining.

I have also used cheap red wine, $3 bottle at trader joes or use what's left over the next day from the previous nights.
