A while back I bought some second hand wooden wall plaques. I painted them and put them aside. This week I dragged one out to use for this project . You could use the Altered Pages Slat Sign . I decided to go crazy and make a fabulous mixed media piece. I am happy with the end results. I began by making modelling paste. It was made with equal parts glue and paint (color does not matter - I used grey acrylic) and then mix in talcum powder until it has the consistency of modelling paste. I used two stencils with the modelling paste to create patterns and rough texture on the plaque, let the paste dry overnight (or longer depending on where you live). I arranged and glued die cut gears , bead trims, gems, keys and clock face. Then painted with black acrylic paint. Three coats were necessary to get good coverage. When dry I painted with metallic paints , letting it dry between coats of paint and colors. Be sure to get in all the nooks and crannies.
