Recovering Spridget seat bottom cushion

I'm "manufacturing" the bottom cushions for my Mk2 Sprite, meaning new pan,
cushion, and cover. I do have a Mk1 Midget seat cushion for a pattern, and can
see easily how it goes together. Any opinion on the order to put it back
together? It would seem the front and sides first, then the rear to tighten
the cover?
