Hello and welcome to PSG.
The background in your sample image is more like old, worn, creased from folding, paper.
I would begin by searching Google Images for similar type textures that could be used.
I found this one in the search which I converted to the base purple color using a Hue & Sat and a Gradient Map adjustment layers.
I would have to add the worn edges with the Brush tool on a layer mask with a similar lighter colored paper texture layer below the colored worn creased paper layer.
