For my parents golden wedding they got
Sponsorship of a golden retriever hearing dog - both because it was golden and because we had one as a child
A sixpence from the year they were married
And one that was just good luck - A framed invitation to their wedding.
For the Ruby wedding I bought some wine from the local vineyard with personalised labels.
For a friend's wedding anniversary they got some vines from the same vineyard - so they get a bottle of wine each year and can 'visit' if they want.
Another year my parents got tickets to a a live version of 'Allo 'Allo - they were big fans of the TV series.
Have a think about what they as a couple like, my parents always had wine in the house so that was a safe bet.
If they like theatre then a 'behind the scenes' tour if they are into football a stadium tour.
If they are gardeners then the rose idea is prefect.
I;ve just remembered for a friend's first wedding anniversary she gave me the keys to her house and I went in a cooked so when they came home all they had to do was press cook on the microwave and take the other food out of the oven, pudding was in the fridge and the starter was already on the table.
