My earlier thread didn't survive the server move. My thanks to those of you who commented in it and gave feedback and suggestions. This one will encompass everything I've learned in my planning, and the revisions I've made to what I'm doing, how I'm doing it, and the order in which I'm doing it.
As expectation, reality, and research come together, my plans have gotten a bit more refined. I am, in the end (however many years hence) going to have five Mandlorian costumes, which isn't as scary as it sounds, as many elements/parts are going to be shared between one or more kits.
Each costume is going to have its own planning thread in here as it moves to the front burner, even though I have the breakdowns for all of them written up. Within each planning thread, I'm going to break the costume down into the relevent board sections with links to that costume's components' WIP threads. Those costumes that share a particular component will have the same link for each costume. i.e., I'm using the same two-part flight suit -- with a second set of trousers -- for three of my costumes, so in the Kyr v1, Kyr v2, and Fenn Shysa breakdowns, the "soft parts" link will go to the same flight suit thread over there. Costume-specific accessories will be in their own distinct threads.
And now, on with the show...
