DE-CLUTTER FLUTTER

I was clearing out a bit more today and came across this. 25 cards which can be joined together to make all the edges match up. In the box there is even a helpful chart with a numbered sequence. It hasn't helped me yet and it has driven me to despair, but I am not giving up yet. When I have solved it, it can then go in the charity bag but not before.

Would anyone like the chart?
