Start by painting the wood frame in any color you choose. Allow to dry completely before continuing. This same technique can be used on a wide variety of surfaces so don't think you are only limited to frames.
Then gather any scrap vinyl that you have laying around. The colors just need to work well together as well as in your home's decor. This one is perfect for those small, tiny pieces that are around the edges of the projects you cut on your Cricut.
Use your scissors to cut the scrap pieces into small triangle pieces. You want these to be varying sizes and shapes.
Once the paint is dry, start peeling the backing from the triangles and sticking them to the painted frame.
Continue all the way around the frame adding your random triangles in various colors.
Once you are happy with the look, your terrazzo inspired photo frame is complete!
