Making art to hang flush with a wall

Instead of having my art hang out a little from the wall like below.

This isn’t one of my pieces.

Or like this.

I had this one framed at a local shop.

I like my art to hang flush against the wall like this.

Eye screws can be inserted on the inside at the back of the cradled wood panel paintings.

And like this.

So here is how I do it.

I build the box frames for my assemblage pieces with an inset of 1/2 inch square dowel that I insert the eye screws to. This 1/2 inch border also creates an edge that the back piece of the art work can be glued to.
