A couple of years ago I glitterized the front of my house. I do a big Christmas display where I have used glitter on my dioramas, candy cane fence, entry way and a 4x8 foot sleigh. This year I will glitterize the driveway side of my house. It is 40x8 feet. I use 4x8 foot pieces of 1/2 inch plywood. When I did the front of the house I broke it down into three sections. For the new project, the design will attach and go together similar to the front, but i'm kind of treating each panel as it's own art piece, otherwise it is a little overwhelming.
First I see a design and colors, I then lay out 2 or 3 pieces of plywood, just to put things right in my mind. I see stuff then draw it out, more of a guide than an absolute. changes come as I go along.
I then see colors and paint the design with colors of the glitter I will use. also, I add dimension. Using a handheld jigsaw I cut out a design at an angle usually. I sometimes cut within these cutout pieces.
once I have a full piece that is painted, it is ready for glitterization.
I do one color at a time, usually starting with the darkest. All I do is paint on Elmer's glue along the design of chosen color. I do sections at a time, not too thick or too thin. I then pour on the glitter, then cover it with newspaper and smush it down with a rolling object, like a can of spray paint. Then begins a new section. Once the chosen color is covered I dump the extra glitter on newspaper that have on the floor. It gets more challenging as i go because the piece gets heavier.
I move onto another color, usually saving the negative space for last. The piece stays flat until dry.
