Large Sand Dollars

Hi,

I am thinking of painting numbers on large sand dollars for my table settings. Anyone know where I can find large sand dollars?

Yes, there is a street in the 20's (I think 27th or 26th but I wouldn't swear to it) between 6th and 7th that is basically all florist supplies. One particular one, closer to 6th ave (D&G or something? Definitely letters), has them. They were sort of expensive but I assume you'll only need around 20.

FM duke for more precise directions, I can't for the life of me remember exactly the name or street.
