How to create a Clipboard Design
Let’s start out by creating a new file. I used a 300×300 pixels canvas set at 72dpi, and I filled my background with white. In a new layer draw a rounded rectangle with #5E3A2E color shade and 65 x 69 px dimensions.
Under Layer Style(Layer > Layer Style) add an Inner Glow and Pattern Overlay blending options to the rounded rectangle layer.
In a new layer draw a white rounded rectangle with 48 x 56 px dimensions, make sure the corners on this rounded rectangle is small.
Under Layer Style(Layer > Layer Style) add an Inner Glow, Satin and Gradient Overlay blending options to the white rounded rectangle layer.

Now use the Polygonal Lasso Tool to create a slanted selection around the bottom right corner of your white rounded rectangle. Then cut the selection and right away go to Edit > Paste, rotate the white piece through Edit > Transform it looks like the rounded rectangle has a fold.
In a new layer draw a small black rectangle with 26 x 5 px dimensions on top of the paper design.
Now duplicate the small black rectangle and nudge it down as shown below. Then in a new layer draw a small gray rectangle on the middle of the black rectangle designs.
