To make this wall art first you have to take some paper. Then apply art masking fluid on its four sides forming a border of almost one to two inch thickness depending upon the size of your paper. Then take any leaf and place it over the paper. Apply spray paint in the color of your choice. When the paint dries remove the leaf and you will get a white silhouette of the leaf. Then peel away the dried art masking liquid that you applied in the beginning and a white border will appear. Frame it and hang it on your wall. Enjoy crafting!
