Exploding Box

Finished Project:

Start with 4 pieces of card-stock (or other heavy & durable paper) that are at least 10''x10'' for the box portion of the project. Additionally, you will also need 1 piece for the lid.

Cut the first piece of paper to a 9 3/8''x 9 3/8'' square.

Cut the to 9''x 9'' square.

Cut the third to 8 5/8'' x 8 5/8'' square.

Cut the fourth to 8 1/4'' x 8 1/4'' square. 

Then you need to draw lines across the paper to split it equally into thirds each way (horizontally and vertically). 

The first piece will be at 3 1/8'' intervals.

The second piece will be at 3'' intervals.

The third piece will be at 2 7/8'' intervals.

The fourth piece will be at 2 3/4'' intervals.

Then, following the lines cut out the four corner pieces on each piece of paper. Then fold along the remaining lines.

Stack the pieces beginning with the largest to smallest to create the exploding box effect. 

Decorate as desired!

For the inside my box i made each inside flap a month of the last year. On the front i put a picture from that month, on the back I typed a little summary of fun things we did that month along with using something (ticket stubs, map pieces, various papers from travels) on the back of the corresponding flap. It made a great anniversary present that summarized our first year in a fun way!

To make the lid:

 

Cut a 6 5/8'' x 6 5/8'' square. 

Draw a line 1 5/8'' away from all edges, then fold along this line.

 

Pinch and tuck in the corners, use tape to hold them down. 

Decorate the top as desired!

For my lid i used the school map with a red X marking the spot of the classroom we met. Decorated the outside of the box and when i gave it to him he was definitely surprised (and stunned happily!) at the contents inside!
