I chose a photo of my son playing with a stack of beakers and picked my papers to match their colours, but I also ensured that all the papers had some white in them to help tie all the bold colours together and to my background.
I used smaller strips than in the sketch, and moved the title over, stamping it in blue ink and edging the top and bottom of the cardstock in the same ink.
