Shells are fun to collect at the beach, but it’s hard to know how to use them once buckets have been brought back. Filling glass bowls with them is pretty but cliche, and also not kid friendly. Instead, we used them with an inexpensive stepping stone kit. All my younger brothers and sisters wanted to help create the pattern. The finished product was a garden treasure everyone could enjoy.
Preliminary designs were traced out on the countertop:
seashells as flower petals and spirals.
We used some leftover glass from a stepping stone kit, and I let the kids make the designs. We then followed the instructions on the cement package, placing the stones and shells in the same pattern and then pouring the cement over them in the frame.
