One of my most favorite websites is:
http://www.splitcoaststampers.com/
It's just too awesome to describe, you'll have to go look to see what I mean!
I found directions there to make a "Mini Pizza Box'' and you can see how adorable they are. These little boxes can be decorated any way you want and can be used for small gifts or treats. You can make two boxes out of one sheet of 12x12 cardstock.
(I also wanted to make a smaller box which you can make two out of one piece of 8x10. For the smaller one, which measures 3"wide x 1" deep, cut cs at 5"x9" and score at 1 and 4 on short side, and
1-4-5-8 on long side.)
For complete instructions go to
http://www.splitcoaststampers.com/. Click on "Resources" and in the search box type in Mini Pizza Box. There is also a link there to Jen del Muro's blog (the designer). She has video instructions on her blog. These are sooooo easy to make and very fun to do!

To add a touch of class, line the box with a piece of cotton or felt cut to the appropriate size.
