From paper to project
Print at 100 % and cut the 180 × 130 mm rectangle.
Mark the centre at 90 mm with a ruler.
Score gently with a blunt tool.
Write inside before decorating the cover.
Check the ink is dry, then add a flat flower or drawing.
Test the envelope fit and sign your name.
Check it with an example
The closed size is 90 × 130 mm, not 180 × 130 mm. Leave at least 5 mm around the text so the fold does not hide it.
If it does not turn out as expected
If the card cracks, test a lighter weight or another fold direction. Do not add layers that stop the envelope closing.

Original design. Match your printer’s paper size and keep the scale at 100 %.
