If you are having a buffet at a rustic wedding, adding twine by itself or with a flower can add an inexpensive, yet special touch that makes your guests feel welcomed. This will set the tone for the entire reception buffet and allow you to save money on other dinner décor.
This pic is from the bridal tea party we just had at our house! Bought the "shiny" plastic silverware.... Serve your guests plastic silverware - just wrap the napkin in a Doily and tie with twine. Add a silk flower for ambiance/romance
Paper doily and twine silverware wrap...could also add tag with name making this a place 'card'. I know you aren't planning a sit down do but you could always have the cutlery wrapped like this (with plum coloured ribbon/string) in a basket or something?... again matching the invitations etc x
