Title says it all, I am going to teach you to make a rectangular box with a lid! This is probably the easiest way to make a simple box; since it involves kirigami. (Not really origami, is it then?) I was taught this in elementary school so it is VERY easy to make. (:
Step 1: Materials
You will need:
-Tape (A substitute for glue, but tape is nonreccomended.)
Step 2: Fold
Fold the paper in half like a book and cut down the crease.
Step 3: Base 1
Use your ruler to measure and crease 1 inch of the paper inward on 1 side.
Step 4: Base 2
Cut 1 inch down the crease you just made. Do the same for the other end of the crease.
Step 5: Step 3 & 4 Continued
Continue step 3 and 4 on every side of the paper, not cutting the sides who are next to a corner that is already cut.
Step 6: Design Base/ Making box
1. Design the base with stamps, stickers, designs, or whatever you want. (Optional)
TIP: Keep in mind the corners will be glued.
2. Glue the corners to the sides next to them, making a box. xD
Step 7: Lid
Continue steps 3, 4, and 5. DO NOT USE 1 INCHES ANYMORE! Instead, use a few milli inches less than 1 inch.
Step 8: Design Lid/ Gluing Lid Together
1. Just like designing the base, only flip it upside down so the deign will show on top of the box.
2. Just like gluing together the base, but glue it together so that the design will be showing on the top.
Step 9: Box-y-ness!
You are now done! Congrats, you have made a paper box xD
