OK - it's official. Time to stop calling it Moretti and start calling it Effetre.
A friend of mine just got back from Murano, and after visiting the factory there - would like everyone to know that the three brothers - which is what Effetre means - would really like to be called by their chosen name. ;-)
And as for the pronunciation - it's "eff - eh' - tray'." For those of us who have been pronouncing it as if it were French (eff - et' - tra) - Ahem! - it's Italian.
Effetre, Effetre, Effetre. We can do this. ;-)
