I use white cardboard. For the box, start with a piece of cardboard of 4x2 cm. The height of the edges is 0,5 cm.
For the cover is, start with a piece of cardboard of 3,6x1,6 cm. The height of the edges is 0,2 cm.
I cut out the corners because when you fold the edges together the corners would be too thick.
I scribe the folding edges. So you get a sharp fold.
I took rice paper to glue around the box. This way you can connect the corners of the box
and the cover.
Before gluing the rice paper to the cardboard I fold it. At the narrow side I left 0,5 cm over so I can glue the edges together.
I glue the bottom of the box and let it dry.
Then I glue the narrow side. The corners are together at the moment as you can see in this picture.
Now you only have to glue the other sides. I worked the same way for the cover.
The box is finished and ready to show the knife.
Have a nice week.
