You start by drawing the measurements of the video tape box on the map. Just lay the box on the map and go around it with the pencil.
Next, you cut piece of the map out. You'll need to cut another +/- 0.3 cm off because otherwise it won't fit in the plastic foil. I would suggest not to measure it, but just cut a bit off and fit it until it's good.
Then you can write the name of the city or country you've visited on the map, right where the map is at the back of the video tape box.
But how do you know where the back of the box is? Just put the map in the foil, close the box, open it again and get the map out of the foil again. The map will be folded a bit, and that's where the back of the box is.
I've used stickers to put "Amsterdam" on the back of this box, but you can also simply write it or cut out the letters of a newspaper. Or just leave it like that.
To finish: fill the box with all of your travel memories!
I've been making boxes of some of my travels and I just love how a collection of them looks!
Are you also such a sucker for travel memories? How do you store yours? :D
