Beautiful, especially when sunlight passes through it.
This is an easy idea what to do with all the clams and beautiful pebbles you gathered during the summer holiday. You will need transparent nylon base and PVA glue.
Cover the heart-shaped nylon with the glue. After that arrange the clams trying to keep the initial heart shape. Leave it for a day or two, it will become transparent when the glue dries up and remove the nylon.
