Heart Window 3D Gift Box

Cut this quick-assembly gift box to hold treats 

or small gifts for Valentine’s Day or any other occasion 

when the heart love symbol can convey your sentiments. 

Model project uses classic “gingerbread and 

icing” coloring. Select the box and accent colors 

that best suit your purpose. Box lid includes 

a heart cut out window that can be lined 

with clear panel for “see-inside” allure. 

On the front, layer the scallop concentric heart “rings”, 

with show-thru tear drop cut outs colored by 

under-lid contrast liner panel. 

Bottom is shaped for quick and easy fold-in 

and latch closure. 

Box measures approx. 4” x 4” x 1.5” when closed. 

ASSEMBLY: 1. Identify and cut the shapes:
A main box hull back, side, bottom and top
B main box hull front, side and bottom
C contrast "show-thru" (white) scallop heart ring
D matching (kraft) scallop heart ring overlay
E contrast teardrop "show-thru" (white) panel
F clear acetate or vinyl window panel
G sides & back icing accent (3)
H front icing accent (1)

NOTE: this box is similar to an earlier circle window
version. Some of the tutorial pictures are taken
from that project's assembly guide.
2. Prepare the main hull shapes by bending back
on all perforation lines for panels, top lid, tabs,
flaps, etc.
3. Overlap the first side seam across side tab to
perforation line, adjust for top/bottom match up,
then glue in place.

4. Position and attach the sides, back and front
icing accent overlaps over corresponding panels
on the hull assembly, with even offset margin
around outer edges.

5. Position hull-matched heart scallop ring over
the contrast heart scallop ring, matching up 
the plain inner edges as precisely as possible . . .

. . .and glue together.
Use a flat weight to press the shape while it is drying
if using liquid adhesive.

6. Position the scallop rings assembly over

the front top lid panel, match the inner plain

opening edges, and glue in place.

7. Position and attach the see-thru window panel

behind the contrast heart panel. 

Use narrow double-sided stick tape

8. Position the contrast panel/clear panel assembly

behind the top lid shape, matching heart plain inner

edges (contrast panel opening has tiniest offset larger).

9. Bend the hull to bring together the second side seam

edges, adjust for alignment, then complete the seam.

NOTE that this side seam can have finger pressure

applied in box's flat configuration. 

10. Close the bottom flaps to form the box:
A) fold the FRONT panel inward, then . . .

B) fold the side panels inward . . . 
C) fold the top panel inward and continue beyond
perpendicular so that the tab slides under the opposite
front panel edge; adjust so that bottom panels are squared.
11. To close the box, tuck the front flange in
and behind the front wall.
Here is the completed box, filled with treats.
