My FI and I are looking into getting 2 Kiddish cups (is that customary to get two and not one?) I think the Rabbi had wanted us to get two. I am looking online for them, but they are just so expensive. Can I just possibly use nice glasses I already have, or is the Kiddush Cup like blessed or something and it has to be a true "Kiddush" cup? I read that families pass them down, but my parents don't have any and his parents are Catholic, so I am SOL with that. Thanks for your help!
