An envelope in exactly your size. Set the width, height, flap, paper and liner, add artwork, export.
The envelope page for a size no preset covers: C6 to begin with, and the sliders run from 110 to 240 mm wide and 90 to 170 mm tall, never taller than wide. The flap depth and the seams follow.
Pick the flap, paper and liner, add artwork, turn it over and open it with the slider, and export a transparent PNG.
As one image on the flat blank; after folding, only the visible outsides of the flaps show it, which is what you see here.




Fixed 3D models of real products, with colours, lighting and animation in the full editor.
