We know Quince is a working man, and a carpenter. We also know that he is less of a fool than Bottom, but still pretty literal minded, and that he doesn't fully realize how silly their play is.

Combining these, I would expect him to give wild and confusing accounts of the stage while the fairies are there, but only a somewhat off description during the final act. He'd make the set seem more glorious than it was, and the props better. He'd make it sound like everything was perfectly proportioned, and he might well discuss the woodworking skill with which it was produced.
