You'll need some plastic animals from the dollar store, some super thin plywood or cardboard, a box cutter, glue gun and paint or spray paint.
First, cut your animal in half. Fortunately, the ones I bought at the dollar store were ridiculously cheap quality and cut easily. After it's cut, paint/spray paint it. I used Krylon's Metallic gold paint.
Next, make your mounting piece by cutting a shape out of your plywood or cardboard and paint it. Then, glue the head onto the mounting piece with your glue gun.
Voila! You're ready to mount! Just use some doublesided tape (if you don't care about having to repaint the wall when you take it down.)
Unfortunately, my wall is still a work in progress, so I'll be posting photos of the whole thing once it's finished (probably this week).
This could be a really fun and easy project to do with kids. I love how sophisticated the gold paint makes the dino heads look!
