If you don’t want to present a voucher in a simple envelope, there are many ways to pack it beautifully. We choose a 3D gift box. You can easily make this box at home, without spending too much on materials.
When choosing the motive make sure to choose something as a picture that is easy to cut out and can stand out, creating the 3D effect. It should also fit to the topic of the voucher. We gave a hotel voucher for Stuttgart as a present and chose Stuttgart Castle as a motive.
This is, of course, up to you and you can let your creativity flow into the design.
General advice: Only use the adhesive in well ventilated rooms or, if possible, outdoors. Wear gloves during the bonding process to protect your hands against contamination. Shake the spray can well before each use!
