I received these pictures from Joy at Applique for Kids using the Karen Capri Pattern. The fish is one of many designs available on her website. She shows how changing a few things can make a different and unique look. She used a border on the ruffle with the same fabric as the fish applique as well as piping along the top of the ruffle.
Adding the same ruffle and applique on the pants ties it all together. With the wavy blue fabric, the fish actually look like it is swimming in the water.
