Coins can be used for diverse crafts and art projects. They are especially convenient for a rainy day activity, because you can probably collect a handful from cleaning out your car or under the cushions of the sofa. Gather a pile of coins and recycle these pieces into a creative work of art.
Wash coins with dish soap to remove dirt and grime. Use a toothbrush to clean the grooves on the both faces and along the edge of the coin.
Make a coaster out of old coins. Prepare a mosaic grout mixture in a bowl. Pour the mixture in a recessed coaster mold. In lieu of a mold, use a round or square plastic container. Fill the container a 1/4 inch of grout mixture. Carefully drop coins on the mixture while still wet. Arrange the coins in the shape of a pattern or design. Add other decorative pieces, such as beads, pebbles or glitter. Let the grouting dry and harden. Gently remove the coaster from the mold.
Decorate a picture frame with coins. Use a wooden frame with flat, rather than rounded or ridges panels. Paint the frame, if desired. Place a dab of hot glue on the back of a coin and press the coin onto the frame. Fully cover each edge of the frame with coins.
Make refrigerator magnets with coins. Place a dab of hot glue on the back of a coin. Press the coin onto a flat round refrigerator magnet. Decorate with paint, if desired.
