INVITATIONS: Be simple and cute with these, and don't forget to island-theme them! Print some up, buy a pack from a dollar store, hand-make them, or try the classic pillow invitation. You could also, since this is a luau, send a passport to your guests! On a bright index card, print this phrase; "One ticket to Hawaii on (child's name) Airlines. Ticket valid Friday at -:-- to Saturday at -:--. Meet at ______. Bring a sleeping bag and pillow and some old makeup." Tie this ticket to an inexpensive, travel-size toothbrush and mail to your guests.
