Answer 1

Just enough to lightly cover the bread, no more/no less, Bunky!  

Answer 2

who in the H butters a sanwich?

Answer 3

What kind of sandwhich?  The only sandwhich I have ever had butter on was a peanut butter and jelly.  I put a thin amount on my PB and J sometimes.

Answer 4

enough to lightly cover each inside side of the bread, spread evenly from corner to corner  

Answer 5

0.5mm in depth, evenly spread over entire slice, not forgetting

the very edges, then again depth would be dependent on the

thickness of the slice of bread, thicker bread = thicker butter.

Answer 7

A light layer of frosting

whatever your fancy
