This is one of my more unusual cards. The "bubbles" were made by combining equal parts water and liquid dish soap, and then adding tempura paint. Then you take a straw and blow bubbles in the mixture until the bubbles foam up and form a large mound above the rim of the bowl.
Next, you place a piece of paper on top of the bubbles and press gently down. The result is what you see on the left. When the bubbles pop, they leave a lovely impression on the paper.
I love these bubble images! They are fun. They have depth and look almost three-dimensional. And they make interesting images for cards.
