Exploding box with A3 card

I’ve got a few minutes between shows so I thought I’d share a quick tutorial for making this exploding box and card!

Start with 3 pieces of A3 card (I used Centura double sided) and trim to:

A) 297x297mm
B) 290x290mm
C) 285x285mm

Score all 4 sides on tri-fold A4 line on cardmaking side of the Ultimate Pro, on all 3 pieces, then cut away the outer corners and layer on top of each other, gluing just the centre segment.

For the lid: use card measuring 7″x7″ and use box lid line 3 inside on the box maker in the Ultimate Pro.

I then used the new Indulgence double-sided cardstock to decorate your box (I used leftover scraps!)

I’ve made a co-ordinating card as well:
