I've just liberated some nice 2x4" timber from next door's skip and it looks substantial enough to construct a new door frame for my daughter.
The old frame however is made from 6x2" timber which seems like overkill. I suspect this may have been due to the door having been an external door originally (and hugely wide). It's now an internal door and is "normal" width.
Will there be any problem using 2x4 timber?
