First measure out how large you want your box to be. I just made mine as big as the box was tall... it made for easy measuring. A shorter piece, just as long as the first piece, made for the lip of the lid.

I folded that part around until I had a circle or oval, and traced the bottom of it on to the cereal box... and that was the lid and bottom of the box.

The only special tool I would really recommend would be a mini hole punch. I bought mine 11 years ago in preparation for our wedding invitations where I had to tie tiny ribbon through two sheets of paper, and around the end of a skeleton leaf. Yes, it was just as tedious as it sounds. lol! But it works great for other projects too... mostly ones that involve a needle, thread, and my 7 year old.

After measuring the pieces and cutting the lid and bottom, I punched holes along the bottom and both short sides of the main box piece. I then secured the thread through both holes and sew down and back up again to bind the sides together leaving me with a ring of cardboard.

Then comes the tricky part... attaching the bottom. I tied a middle hole to the back next to the seam, then I tied hole that was directly across from it to the front. Then I sewed all the way around... not being picky about the way it looked... until I met up at the other tie. I tied it off, not cutting the thread, and then continued around until I got back to where I started, and tied it off again. This part really doesn't have to be neat. I didn't have any problems skipping a hole or two on each box, or doubling up if I needed to... it doesn't take away from the box at all.

I then did the same thing with the lid.

Put the two together and you have a whole mini hat box!

Then all that is left to do is decorate!

This is one that my daughter and her friend decorated for their "someday drive through lemonade stand".

And here is the one I pictured up top.

I really love how it turned out.
