I saw this sketch and immediately thought of a background piece that I had made ages ago that I was waiting for the right inspiration to use.
I spent quite some time trying to fit the curve onto my background but it always came back to looking like a sunrise so I just went with the flow.
The background card stock is black with metallic paints smooshed on it, not sure exactly how I did this but I did put it through a Sizzix embossing folder (Texture Fades Rays and Retro Circles set) which I appear to have put white paint in to emphasize the embossing.
The circles are cut with a nesting set by Photo Continental (sold by Craft Giraffe). The sentiment is from a Penny Black set called 'Hooray'
