The card was only 4 1/4" x 6" in size.  I made it smaller than my usual size--which is 6-inch square--because I was going to use only one Mini Magnolia image on the card front.  I thought the 6-inch square card was to large for it unless I heap all kinds of embellishments on it--more than I already did...LOL. 

Anyway, I was asked to do a tutorial on it (Donna, this is for you), so here goes...

Materials required
2 pieces of cardstock 8 1/2" x 6" each
4 1/8" x 5 7/8" designer/patterned paper to decorate the front
8 1/2" x 6" designer/patterned paper to decorate the inside
Other materials to finish decorating as you desired, eg. coloured images, flowers, ribbons, bows, pearls, etc.

For those of you who need step-by-step instructions, here they are...

INSTRUCTIONS

Step 1
Score an 8 1/2" x 6" cardstock midway at 4 1/4" and fold.  This is for the front cover.  Put aside.

Step 2
On the other 8 1/2" x 6" cardstock, pencil-draw horizontal lines at 2" and 4" from the top.
On the first horizontal line, mark at 3 1/4" and 5 3/4".
On the second horizontal line, mark at 3 3/4" and 6 1/4".

Step 9
This is the easiest way I can think of of explaining how to cut out and trim your designer/patterned paper to decorate the inside of your card.
Draw the cut and score lines shown on the template on your designer/patterned paper.

Step 10
Using your ruler and craft knife, trim away about 1/16" for the outside paper edges and both sides of every drawn line, a shown below.

Step 11
Apply glue to the back of each piece and adhere to card inside as shown.

Step 12
Apply glue to the back of the 4 1/8" x 5 7/8" designer/patterned paper and adhere to card front.  And voila!...you're done.
