I love the "cool" (pardon the pun) layout of this card... Nicole Heady of Papertrey Ink gets the credit for this... I just switched it up a bit. You take a Window Word Punch and punch the flap... then just draw some guide lines with a pencil, and with your self healing mat underneath you use your craft blade and a straight edge to cut the slits. The paperclip fits right under the flap securing the card shut! I used a Coluzzle to make the rounded edge on the fold over part.
A clear square button was used as the paperclip topper. I pressed the button into a versamark pad, coated it with Heat and stick powder, melted the powder with my heat tool and then covered it with Dazzling Diamonds glitter. A second quick blast with the heat tool and the glitter is set!
The "cubes" below were created the same way. I coated a piece of Whisper White paper with the Versamark/Heat and Stick Powder/Glitter.
