Having done quite a bit of fiberglassing recently, I tend to go with the longer (wider) piece on the first layer and then progressively narrower pieces on top, when doing open lay-up (i.e. not vacuum infused).

The reason being is that going short -> long yields air pockets in the areas within the laminate where the wider pieces transition over the shorter pieces.

I've seen it reccomended both ways is why I asked. I know FAA is small to large but they're typically bagging if memory serves (and as you said).

Honestly I don't know that any of us are stressing the materials enough to have it actually matter all that much... as I think back to my boat with minimal structure in the tabbing and no caps. :LOL:
