I have also been thinking about using pins to float paper off the wall, and found good examples of that being done effectively in the works of Hope Hilton.
I enjoy Hilton's installations for her use of simplified, symbolic shapes, and her way of grouping and spreading out the shapes to create feelings of crowdedness, isolation, sameness, and organic change. The way these pieces float alone from the wall also gives the sense isolation and tension, suspended in mid-air by one vulnerable pin. Many of my installations use grouping and repetition as well, though the shapes I create are more varied in color, shapes and texture. It is intriguing to see Hilton's way of working, though, with clean, consistent laser-cut shapes and colors.
An artist that demonstrates color and texture quite well is Britt Bass. I found her work by google-searching paper sculpture, and was very inspired by her beautiful installations, full of movement and found materials.
Another artist who is using found materials and making incredible large-scale installations is Abhidnya Ghuge. It seems she's been working with paper plates quite a bit, creating installations that cling to the wall in certain places but also hang from the ceiling in others. I am love the colors, shapes and depth she creates by transforming and amassing plates of different colors and patterns. I enjoy that she is creating actual new environments in some of her work, not just art on a wall.
