I think this is a super cute idea for a kitchen tea. You get these sticks at your local craft shop...
Ask each guest to write an idea for date night on a stick with their name.
It can be anything from cooking dinner together, your favorite restaurant you want them to try out (even write the telephone number on there to make it easy for them), go for a walk on the beach, read a book together, be creative.
The couple will then have a fab date night and think of you... or you can even ask them to send a photo!
You can also use it at a wedding asking the guests to write something to keep them busy, while the bride and groom are taking photo's!
