Concertina card/book tutorial

Hello all you lovely Peeps, I have a little project to share which after finishing thought it might be useful to do a tutorial as there are always new crafters in blogland, so I have made a start on another and took a few photos along the way.

I know the shape is not a new concept and it's years since I used it in a class, but it sort of came back into my mind the other night when trying to think what I could do to keep my crafty mind occupied until I can stamp again properly. And Ignacio's lovely Nicecrane Christmas images are perfect, I used images from the Old Merry Christmas and Adorable Christmas sheets. 

Cardstock: Three 8"x8" pieces 220/250gsm for the main card and two 4"x4" pieces of a heavy weight for the front and back panels.

Coordinating DP's: Two pieces 5"x5" for front and back panels, ten 3.5" squares, four left whole and six cut diagonally.

Scoreboard and scoring tool, glue and choice and images, ribbons etc., to decorate.

Score each 8"x8" square as indicated above I have made the photo's large in the hope you can read the directions and my current appalling writing - things can only get better

Glue the three pieces together as indicated above

Now fold each scored line both ways to make the whole piece more flexible and then into the finished shape

This is how I deal with my box lids and the same process works for this project and below the  finished panel ready to be adhered to the main piece. And finally add all the internal square and triangle DP's sections and decorate. 

I am not totally convinced my explanations are clear so please do mail me if you want to check on anything.
