When my friend got married I printed a photo of her and her husband from the night they first met (which was in a bar). It’s actually a nice photo and they were really touched by it and now have it in their living room.
You basically upload a photo to the Royal Mail’s website and you get a sheet of stamps with your photo attached to send out. Great for wedding invitations, christening presents, valentines – anything! For my brother’s wedding, I got a printed set of stamps with him and my sister in law on so that they could use them to send out their thank you cards. Was a really nice idea.
In many parts of Europe it was traditional to supply a newly married couple with enough mead for a month, ensuring happiness and fertility. From this practice we get honeymoon or, as the French say, lune de mile. So buy a mead brewing kit, or brew some mead for the newly married couple for a wedding present.
