1. Gather your supplies: a framed mirror, craft glue, a paintbrush, and seashells of various kinds and sizes. Repeating similarly shaped elements, such as sand dollars or sea urchins, and using a limited palette will make the piece look harmonious.

2. Place the larger pieces on the frame first, then fill in with the smaller ones. Applying the craft glue to the shells with a paintbrush makes it easier to be precise on uneven contours.

3. Hang the mirror using a picture hook and a hammer, or lean it on top of a dresser, on a table in a hallway, or anywhere else you would like to see a seascape.
