Open the PSD file of Modern Messy #3 and drag the layers into your layout. I colored the paper layers in the template a light craft color. Now, place the rose and leaf templates from Floral Pattern #5 above each paper layer and apply clipping masks to the template layers. Your Layers panel should look similar to this:
To add a bit more fun to the paper, you can place text from Brush Set: Manuscript over the template layers. Finally, move the “messy border” layer from Modern Messy Template #2 to the top layer so it can frame the whole page.
