does anyone have a pattern or template for a barn made out of RKT?

or know where i can get one?

I don't know where to find a template, but it is a fairly simple shape. You could draw it even if you are not good at that sort of thing - like me! Use poster board and make the walls, then do the roof a little large and trim it until it seems the right size. You can use the poster board as a guide.
