After several attempts, I finally came up with something for the challenge. I created the background page with ribbons done with cass-RibbonFactory Script. I draw some lines (Pen Tool) inside the outline of the letter and created this way space for the photos. I select the outline > Effects >Texture > Sculpture.
I clipped the photos with cass-ClipToIt Script. Very helpful and saves time. The 2 sequin elements are freebies: cass-SequinWeather
