I have seen some designs, that required very very tiny parts, that had to be extremely precisely made, but since i do not have access to neither laser cutters nor CNC machinery, i decided to make a simple design, that i would be able to make, without having to invest in additional tools or materials. I am pretty tight on my economy, so basically anything expensive was ruled out. I also set the criteria that the picture had to be centered, not on either half of the heart, which actually later lead to accidentally figuring out how to put 2 images in the locket.
Again because of my limited selection of tools, i decided to not make this a necklace pendant, but a 5*10 cm box instead. This was the only way so far that i could get the dimension relations as a wanted, and still have a decent size picture in the middle. It is still small, and has a nice size, fits nicely in the hand, and after several steps in finishing it up, it ended up having a bold and soft surface that i am very satisfied with.
I have uploaded this in the Valentine's Day contest, so if you like the project please vote for me :)
