I bought small glass vases for the Kiddush centerpieces. They are about 4" in diameter at the top, fluting up from about a 3.5" base and approximately 4" tall.
My plan for our son's Bar Mitzvah is to fill these with wrapped candies in his theme colors. I also have a cardboard round matching his theme to put underneath the vases.
I've already spoken about this with a couple of our other Mitzvah Moms, and they are going to share in the use of these.
I think anything that we can share and use multiple times is beneficial.
What do you think? Would you like to use them as well? How will you fill them?
