Here are my instructions for my "3D Concertina Window Kits". I hope that you like them!! These kits are very simple to make and produce a 3D tunnel effect due to the concertina edges.
The great thing about these kits is that they don't require any double-sided printing, yet all of the edges and sides of the finished card are printed (apart from behind the front panel, but this is barely noticeable).
