I have made my goddaughter's children all a 3D picturescape, so when it came to Braxton's (a one-year-old boy who loves Ducks) I made a duck. I used 3 different SVG files to make my image. I started by making a simple black frame 10.5 x 10.5" to fit inside the 12 x 12 shadow box frame. Next, I created the adorable duck with an SVG from My Scrap Chick. I cut him out and layered him uses 3D foam tape and layered him both behind and in front of the black frame. I added the bullrushes SVG from Cricut Access, and finally using vinyl, I mirrored the SVG sentiment from Etsy and attached it to the back of the glass.
This is a screenshot of my created design in Cricut's Design Space.
