Will you please attach the document template for your postcard design? B'cuz on vistaprint there are different size of post card with both horizontal & vertical folded layout. It is better if you decide first the size & layout of postcard.

I''m not sure what you mean by document template.  The postcard on VistaPrint will be their jumbo postcard.  The dimensions are 6 inches high x 11 inches wide.  Hope that helps.

Pls guarantee your contest

Thanks
