I really like this card for using DSP and a nice focal panel.

Clue #1  Vertical/Portrait card, Gather your supplies: 

Colored Cardstock: 
–  1 @ 5-1/2 x 6-3/8, score on the long side at 4-1/4

–  1 @ 3-1/2 x 4, score at 2 on the long side, attach on the outside flap of the card base, putting the fold over the edge of the card base BEFORE adding DSP

Coordinating Colored Card Stock:
–   1 @ 3-1/4 x 3-3/4, layer this onto the 3-1/2 x 4 piece above, with adhesive ONLY on the bottom half

Designer Series Paper (DSP):
–  1 @ 1-7/8 high x 5-1/4 wide
–  1 @ 1-1/2 high x 5-1/4 wide, layer this on the 5-1/4 x 4 White/Vanilla piece, attach inside card

White/Vanilla Card Stock (CS):
–  1 @ 5-1/4 x 4
–  1 @ 3 x 3-1/2, This is your focal point.  It is 3 wide and 3-1/2 tall.

Embellishments small to medium:  
use something that goes along with your DSP and something small to make the front panel stand up and it folds flat to mail
