I got bits of very thick corrugated cardboard from a friend after he moved and turned them into containers.
The branding and technical details on it were designed by myself and printed on decal paper.
The results is still a bit of a mixed bag:
>The larger decals broke down during transfer. So I had to cover some of the containers in rust, to hide the defects.
>Even after spraying varnish over them, you can still see the transparent part of the decal. I don't know how I could improve this.
