Hee hee ... If I go for an A3 version it'll be big enough to get in and go walkabout in it.
Actually, at first sight, I thought "Oh yes, I do want this." but I'd much prefer it to be 4 to 5 inches tall. Of course, there are no clues given as to the size until after you've figured out how to download it and open it up in Pepakura.
Strange?? Pep designer gives the dimensions in inches and Pep Reader gives them in mm. I guess it's changeable somewhere in the settings, but I ain't changed nuffin' ... Honest Guv.
