I wanted the look of a headboard on the wall behind my bed, so obviously, I turned to Pinterest for some inspiration.
I decided on something like the latter two photos.
I bought a bunch of wood-framed mirror squares from Ikea, and actually covered them in slightly larger squares of fabric, securing with hot glue.
You could add a layer of batting to make them softer and more plush-looking.
Note: I liked the look of actually leaving a couple mirrored squares as is.
I then hung each with a picture hanger nailed to the back of the wood frames.
Using this neat trick (found on Pinterest, duh!) to hang the frames.
Unique collage headboard! So there.
