Last night I realised that it would be a lot stronger if the ends had tabs that folded round and could be glued down the middle of the sides (as a sort of 3 layer sandwich). The goings on in the corners will be hidden by the overlay bits anyway.

So here is rev 2. I've also added an explicit creative commons license to it so people know it can be reused and how

The previous one will work on thin card, this one won't as the thickness is only going to work for paper. If you are using thin card you don't need the extra tabs so you can cut them off !

Fold up the ends and glue them, then fold up the sides. the light grey tabs each end go into the middle of the respective side to hold it all together firmly.

and have fun fiddling - if someone wants to make a pro wedding one feel free (please though don't make it the Peco purple as a matter of taste !)

You can actually get very good quality off a modern printer and a bit of judicious use of painting tools. This is one I did a while ago as a bit of fun for a ferry van conversion (sides fit the Mill Lane Sidings ferry van)
