Here is a customizable photo frame. Here you have the representation with a heart, but you can make it with anything; you just need to put supports in the outline of the frame.
For this frame, you will need:
Then add 2 sheets of 1mm Plexiglas each with a size of 125/168mm, as well as for the paper.
Now you just have to assemble it, and you're done! You can now make a double-sided frame for your best moments.
