Wedding proposal: 6 years in the making

Watch the moment this man cleverly uses a photo to propose to his girlfriend.

The YouTube video reads: "We've been dating for 6 years and about a year into our relationship had the idea to document some highlights of our lives by taking pictures with letters.

We wanted to prove that if one day we got married... that ''we always knew''.

What my girlfriend didn't know is that for our final letter (which we had done in our home town) I had something bigger planned. Enjoy the video."
