Here's a little tutorial I put together in pictures on how to make a takeout box from one sheet of card stock. I will do my best to explain the process so please bear with me. I would use pretty colored card stock, but for this tutorial I though the cream would be less distracting and easier to see.
First you'll want to cut your card stock into 4" sections so you have 3 (4"x12") pieces. cut 2 of these pieces into 4"x9" save the remaining 2 (3"x4") pieces for the top flaps. see photo below.
Next we'll need to score our 4"x12" paper at 1/2" and 4 1/2" on each end. Then score at 1/2" between the
4 1/2" and the 7 1/2" score lines.
As the photo above shows we've taken our rectangle and trimmed the sides between the 1/2" score line at the ends and the intersection of the 4 1/2" and 1/2" score lines. This creates a slight taper which gives out takeout box it's classic shape. I apologize if this part is unclear, enlarge the photo to see my written marks and better understand the photo. NOTE: be sure to fold your score lines.
Next take your 4"x9"rectangle and make a mark at1 1/4", 2 1/2", 6 1/2" and 7 3/4" at the top of your card stock. Then at the bottom make a mark at 3" and 6". Draw a line between the 2 1/2" and 3" marks and then between the 6 1/2" and 6" marks, from top to bottom. see photo below. Then make a mark 1 1/4" from the top corners down the side.
You will cut away where where the photo says to cut away and your piece should look like the next photo.
then fold your score lines. Shown below on the left I have folded the my score lines and on the right I have trimmed the excess at the top.
Next apply adhesive (I recommend sticky strip) as shown in the orange.
assemble as shown...
making sure your flaps are on the outside (like a takeout box)...
I attached an eyelet using my crop-o-dile, I just went in as far as I could with the 1/8" hole punch and centered it.
Then you'll take the flaps and cut a slit in the center about 1 1/2"-2" long if you would like your box to close differently or don't want to cut the slits you could always seal it with a sticker.
Attach the flaps and string some ribbon about 15" into the eyelets and make a knot to secure.
Fill with goodies and decorate the outside with fun embellishments. Enjoy!
