A4 twisted pyramid decoupage sheet by Design House as pictured. containing a numbered 3D pyramid project and complementary design elements.
Cut out all the different sized shapes of the image, then layer them on top of each other with foam pads or silicone adhesive, at a slightly twisted angle, starting with the largest at the base and the smallest at the top, to create a 3D pyramid effect.
This is a traditional decoupage sheet, so scissors are needed!
Web image is watermarked by the manufacturer - the decoupage sheet itself is of course not watermarked.
