MAKE A BOX CARD FROM A SQUARE CARD

Here's an easy way to make a folding box card using a pre-existing square single fold card.

Cut a double-sided tape width of card of the front of your card, measure and score down the corresponding edge of the card back.

Measure the width of the back after the edge has been cut off, and score a line half way.  Do the same between the fold and the scored edge of the front (the four panels you've created should all be the same size).

Decide how big you'd like your flaps to be.
Cut down along the folds to this length and score along the edge you'll be folding down.  (You can fold all four down, or leave the one at the back sitting up.  Cut across to the edge of the back panel from the last cut so that you are left with a tab.  Score Put some doublesided tape on this tab and stick the panels into a box shape.  Make two or three little rectangles to fit the inside of the box, bend the edges into tabs and secure with the flat side facing the front.

Now all that remains to be done is to go wild with the decoration........in this case a Sparklelight 3d sheet from Regal Craft Cards, spread over the card, with elements attached to little "sticks" made of acetate so they appear to be floating above the main part of the card
