And this is how I did it:
You will need cardstock 13x28cm, scored at 13cm and 15cm
4 x 11.5cmx 18cm pieces of cardstock, scored every 2cm.
Decorative items - tape/tissue/design paper, flowers, brads, gems - anything you want really.
Concertina fold the 4 p11.5x18cm peices of cardstock like this ...
Now you need to assemble the 'box' - take 2 of the concertinaed strips and add wet glue or glossy accents to one of the edges of each. You the need to slide them together so they form an L
I prefer to use glossy accents as it dries much faster - if you are using wet glue you may want to let each corner dry before doing the next.
Now to decorate - I decided to use tissue tape,but you could use any papers you want, sprays, paints. I covered a square of cardstock 12.5cmx12.5cm with the tape, and also stripes of card to cover the binding and the tops of the 'box'.
I then used distress inks to colour the cardstock and tape, and let it dry. Distress inks give quite a subtle colour - stains will give you a darker effect.
Then I covered the box tops ...
Onto the decoration - I decided to use a couple of flowers, so I cut flowers out of covered and stained grungepaper, hession and linen.
