Hello folks -

My collection of scrounged bottles has been cleaned, polished and ready
to go.

The opening sizes on the bottles vary: 17 mm, 18 mm, 18.5 mm and some 19
mm.

What size corks should I use?

I'm guessing that #9 would be a tight fit in the 17 mm openings, or will
one size in fact fit all?

I've been told it's better to ask a stupid question than to male a
stupid mistake!

Thanks.
