On the front, place tape on the inside surface of the narrow flap. Adhere this flap to the card back on the tall side edge, aligning the flap’s crease with that edge. On the card back, place tape on the outside surface of the narrow flap. Adhere this flap to the card front, aligning the crease with edge. This will create a box shape.

On each brace, place double-sided tape on the outer surface of each end panel. Cut three 3¼"x 5/8" pieces of Orchid & Cats striped paper and glue one centered on each brace middle panel. Adhere the braces to the inner box sides on the inside, spacing them ½" apart.
Use double-sided tape to attach the large window die-cut to the back so it extends 1½" above the top edge. Foam tape a 1" butterfly die-cut to the window at the upper left. Attach the sitting cat to the back brace on the right and the sleeping cat to the middle brace on the left. Attach “life is better with cats” die-cut to the front brace on the right.
