"When ordering these place cards I had requested them to be printed in dark gray with my own plans to use a lighter paint pen to write in guest names. I was advised by the design team that this has been tried and doesn't turn out well so I went with the escort cards as shown. They look beautiful in person and I have the names done in a dark metallic gray pen... It Looks Great :)"
