I am making a floor standing mirror. The frame is complete and I now want to create a double rabbet for the mirror and back to fit into. I’m still pretty new at this so wanted to ask a question on process before I jump in and do it incorrectly. Should I be scraping/sanding the mirror frame down to get ready for finishing before I create the double rabbet, or should I create the double rabbet and then prepare for finishing, or does it matter? Thanks for your help.
