Well this is one of those times.
Take a 9" by 12" piece of scrapbook paper.
It needs to be a decent weight or it won't hold.
Score at 3" 6" and 9"
Score at 1 1/2". 4 1/2", 7 1/2" and 10 1/"2.
Now using your cutter cut a tiny bit of each side of you paper on the 9" it really is like 1/16".
Your card is now 8 7/8" by 12".
It has to be a bit of each side as this makes the box lid fit over the sides of the box and stops you having to fiddle with odd measurements.
All the folds are folded like valley folds,
This means wrong side to wrong side.
If you do this and crease them all you will find the design makes it self once you do the 8 cuts you need to finish..
The next bit sounds odd but is very important.
Measure along the top of the 12"
and mark 2 1/2" and 9 1/2" mark top and bottom.
Now draw a line to make these points meet.
You will be cutting this line.
You cut down to the 1st score line
stop turn the card stock round
and cut to the other score line.
You cut four times in all.
If you look at the picture it may explain this better, what you want to do is cut the score line you meet
to make a T shaped cut.
Your lid will be like on a pizza box.
I did mine first and used wet glue to stick them down as in the photo.
When you lift the remaining sections it
gives you the sides of your boxes.
The sides will over lap and you just glue them together to give you a little box in the center.
The lids then life up to meet in the center.
So I decorated mine.
The inside of the lids is 3" by 3".
4 lots of 3" by 3" for inside the box as well,
you may need to take a bit off so it fits snug.
The outside bits of the lids are both 2 7/8" by 2 7/8".
The side panels are 2 7/8 " by 1 3/8"
You need 6 in all.
Then just add ribbon to close.
