If you click on the instructions below and open them they will become clear to read.
I have scored all along the centre so that the top sections drop down but it is possible to leave one at the back so that it stands up, it just depends on the effect required.
As you can see with the box I made, all the lid section drop downwards.
You can then add what ever embellishments you wish by attaching them to the inserted strips.
I have not given measurements for the matting and layering as you may not do it quite the same but I took off half a cm. for each mat I made.
Thank you to all the kind people who left comments relating to this box.
