I have been offline and don't know if it's been shared already but here's a quick and easy box using the Sizzix Scallop Envelop Bigz Die and Big Shot.
I ran the Chocolate Chip cardstock through the Big Shot and used Snail adhesive on the tabs, scallop edge up. Folding the tabs down when sticking them together helps in aligning them quickly and evenly. When adding the DSP, just fold the box flat before closing up the bottom.
Go to my blog for more pictures... I put up a quick pictorial "how to" on this fun box.
Here's the link to the tutorial.
BTW, turn off your sound... I have music playing.
