kellydave4ever's Pink wedding

My place cards have a black and white damask border around them, with their names written in black. They are going to be laying on the napkins and and being held down with a Polished Black river rock. The black rock will have a monogramed "B" on it in crystals.

i have the cards, purchased the rocks and am now looking for a place that will sell the letters, but most places sell letters as a whole alphabet set, i just want "B"'s anyone know of a place??
