Our kids were looking for Christmas present ideas for their grandparents last year and I wanted them to make homemade gifts. We have a never ending supply of large rocks in our yard so we went hunting for flat ones to paint on. We purchased acrylic paints at the craft store and let them paint designs on the rocks. Once the paintings were dry, we sprayed them with a few layers of clear coat. These rocks can be used for so many things: door stops, paperweights, yard art, etc.. These gifts are personal and can be enjoyed for many years to come.
