Have a spot of tea...on your invitation. Mount paper made with green tea onto a card, then affix a tea bag. Staple on your own tab with a clever message, such as "Gimme a Tea" or stitch a guest's initial onto a linen napkin with the string from a tea bag, then write her name on the tab to create a place card.
