The "must use" was the turquoise blue background, which has the image of a sweet little fairy in it. I'm not a blue person as such, but the shade of this blue is quite pretty, and as she seems to be sitting in water with something in her hands, my mind's eye saw shells and an underwater type scene. The prompt word Magical helped that vision.
I started with three layers...brown felt, the blue background and a pale limey green netting. I free-sewed around the edges to make a seaweed effect, in different coloured cottons then roughly cut out the part of the netting that revealed the fairy making the edge look chopped. Then I added thick strands of embroidery threads throughout the seaweed, and sewed on beads and tiny shells. The fairy holds a gold starfish in her hands. I've also glittered up her wings.
