This is a great home craft project, especially suited to less arty beginners, which can be used to memorialise special locations, commemorate intimate relationships or track travel.
There is a free silhouette cut out that can be used for this activity, download it here created by smile for no reason. Alternatively, a heart drawn by free hand could be used.
In my example, a heart was created from three separate locations: where we met, where we got together and our first home. When we move house, I can glue my old keys to add a personal touch to the picture. With a blank canvas left, it can have dates added below at any point.
