The boxes can obviously be made from any greeting card, not just Christmas ones. These make great little gift boxes or can be used to hold office or craft supplies like paper clips, tacks, push pins, beads, etc. Christmas ones can be hung on the tree or piled beneath a miniature tree.
Here's what you do:
1. Cut apart a greeting card along the fold, separating the front from the back.
2. Start with the back part of the card. Using a ruler, draw lines from corner to corner on the unprinted side of the card to form an X. The center is where the two lines of the X meet.
3. Fold up each of the four sides of the card to meet the center of the X. Crease the folds well.
4. Open the card back up to reveal the creases you've made. Now, holding the card vertically, carefully cut on the two vertical crease lines at the top and bottom of the card, just to the point where they intersect with the nearest horizontal crease.
5. Fold in the tabs you just created by following step 4. You can now see how this is going to form a box. Tape the tabs inside the box. (You may find that each end of the box -- the part between the tabs -- stands up a bit higher than the rest of the box. If this happens, it is not a problem. You can simply fold the excess down inside, over the tabs, and tape it in place. Or, if you prefer, you can simply trim off the excess card before taping.) You have just made the bottom of the box!
6. Now, repeat steps 2 through 5 with the front part of the card, which will make the top of your box.
7. Obviously, this produces a box top and bottom which are exactly the same size, which sometimes means that the cover doesn't go on too easily. Usually, if you just squeeze the sides of the box gently, the cover will go on just fine.
These directions look far more complicated than the process actually is. I've made loads of these boxes with kids over the years, and it really is easy enough for even a 5-year-old to do. So have fun with these cute little boxes!
