For one 12 x 12 sheet
Cut 2 pieces of card stock to 5 1/2 by 6 inches. Cut one piece of card stock 12 x 3 inches.

For two 8 1/2 x 11 sheets
If you are using two sheets of 8 1/2 x 11 to make your project, cut 2 pieces of 5 1/2 by 6 but cut the long piece 11 x 3. You can make them smaller or larger than 3 inches if you want. Depends on how deep you want your box.

Score 3/8's inch on each side of the long piece (12 x 3 or 11 x 3). .

For 12 x 12 Sheet
Score 3 inches in on each side crossways on the long piece (12 x 3).

For 8 1/2 x 11 sheets
Score 2 1/2 inches in on each side crossways on the long piece (11 x 3).

Notch out triangles where you've cut in at the cross sections being careful not to cross the 3/8's score line or you will cut into your box.. See photo.

Place Sticky Strip on the 3/8's edges.

Fold at the score lines.

Place one of the 5 1/2 x 6 inch pieces evenly on the Top Note Die.

Run through the Big Shot Die Cutting Machine

Use the Corner Rounder on the top corners of the 5 1/2 x 6 pieces. The top corners only! This is an optional step:)

Remove the Sticky Strip from the middle of one side of the long strip. Apply the back 5 1/2 x 6 piece.

Remove the Sticky Strip from the other side and apply the 5 1/2 front piece (where you have cut out the top note).

Remove the remaining sticky strip and adhere the sides.

Your gift box is almost complete.

Cut a 5 1/4 x 5 3/4 piece of acetate. (Stampin' Up! calls their acetate sheets, Window Sheets.) The clear ones are on page 158 of the catalog. The printed window sheets are on page 169.

Add a few small pieces of Sticky Strip to adhere it inside of the front of your box.

Your box is complete! These are a great size for 5 1/2 x 4 1/4 cards and envelopes or any type of small gifts.

Decorate as desired. You can adjust the depth of the box. You can also adjust the height of the back of the box if you want. You can see how I did that on the purple one.
