Cut out 2 short pieces, 2 wide pieces, and 1 bottom piece out of each of the three fabrics (pattern, plain and stabilizer). Cut out a handle piece of the patterned or plain fabric depending on what looks better to you. (Using the pattern makes it more subtle while using the plain fabric creates a bolder statement).

Using an iron (or other method specified by the product you are using), attach the stabilizer fabric to the wrong side of the plain fabric.

On the stabilized plain fabric, attach sides A to A, B to B, etc. with the good sides of the fabric facing inside towards itself and the stabilizer fabric on the outside.

Fold the handle fabric in half and sew along the () edge, Pull the fabric through to create a ribbon. Cut each edge to have a center point (like a triangle). Fold over to hide the triangle and center on a short piece of patterned fabric.

Following the same pattern from part 3, attach the patterned fabric with the good side facing inward. Turn inside out so the stitches are visible from the outside.

Place the plain fabric box inside the patterned fabric box. This should hide all sewn edges and the stabilizer fabric.

Place the ribbon along the top edge of the box using it to encapsulate the top edge of both boxes. Sew along the edge.
