Shells can be decoupaged with stylish napkins (as seen in this DIY seashell trinket tray by creator Bek Marsden) or painted with acrylics. A delicate, gilded edge is the perfect finishing touch.

Make home decor products like shell-embellished mirrors, fireplace surrounds or picture frames. Other good ideas are shell-covered jewelry boxes, planters and seashell-filled lamps.
