Depends on what you are making. For me, wallets, holsters, cases all differ in the order depending on the end-product and/or the effect you are trying to achieve. many times, it's cut, dye, glue, sand edges, groove, stitch, edge, burnish apply finish. on some products, there are some parts that will need the edges finished before assembly because there will be no access to those edges. You will have to plan the process before starting. Just think it out, draw it out on cardboard as a mock-up before using good leather. I have had many an "oh sh*t" moment in the middle of a project. Then you have to step back a try to think of how you can (1) salvage the piece if possible, and/or (2) not make the mistake again on a similar piece. Good luck. Just dive in! I have destroyed many cereal boxes and poster boards doing mock-ups to make sure my process was going to work.
