For my pictures, whether hueforge or other things, I have designed these small hooks which can simply be glued or screwed invisibly onto the back of the object to be attached and can be attached to the wall in an optically "floating" manner.

You have the option of sticking them to the wall with 3M tape or attaching them with screws.

The part that goes on the back of the picture (or other things) can also be attached either with 3M tape or with a small screw.

Have fun with it and feel free to show me your results.
