The anniversary of your first date comes closer and you want to make a special present for the beloved? How do you like the idea to preset him/her a symbol of eternal love and happiness?
So, if you are already interested, then hope you'll like my idea.

First of all, you should create such symbol. My idea is to present sand-glass.
The sand in this hour-glass never ends and for this reason it is considered to be the symbol of eternity.

To make the gift and idea more creative, you can do the following: do not buy this glass, but make it of roses, for example. Put roses on the floor in the room in the shape of sand-glass and don't forget to explain the meaning of it to the partner! Tell that your love will never end, just like the sand in the hour-glass

You can also do this symbol of cream on the cake.
Or arrange balloons this way.

This idea may be different each time, cause it depends on your imagination
