Lots and lots of matting and layering, with the design made up as I went along! I only had 2 sheets of that particular gingham card in my stash and it matched my aqua cardstock and ribbon perfectly so it was a while before I committed to where I was sticking anything.
The little image is from Digistamp Boutique - Simpy Baby Collection, so simple but so cute, and the wording panels all done on the PC.
And this is it opened - I made a mini-box inside too which was intended for her to hide her gift of money inside, but I think may be too small?
I'm considering making a matching card with pocket to tuck inside the lid of the larger box - watch this space!
Edited to add - I went with the matching card idea, with a little pocket on the inside to tuck a cheque into, using some of my leftovers from the box.
And I'm pleased to report the customer loved it!
I'm entering this into the Digistamp Boutique Monthly Challenge for September.
