Buy enough small gourds and pumpkins so you have one for each guest attending Thanksgiving.
Print out a triple-spaced list of all the guests' names in a lovely font on the computer in black or brown ink. Use a cardstock-weight paper in an ivory or other off-white color.
Cut each name out individually. Cut an inverted "V shape" into the ends of the paper so it looks like the ends of a ribbon.
Using pins with fancy pinheads (anything will do except for sewing needles and standard metal pinheads), pin a hole through the top of the name tag and stick into the top of the gourd or pumpkin.
Place the gourd just above each guest's plate, or on top of a folded napkin in the middle of the plate.
