Sorry for the crappy pic. I'd take more, but it HAD to be in the mail the morning after we made it. :-)
I just had to share:
Last night, the boy and I spent the evening making an advent calendar for his sis out of: A bag of mini Nerds boxes, a half-piece of poster board, some wrapping paper, packing tape and my trusty inkjet printer. I'm working on posting pics, but the upload is really really slow tonight. Anyway, it's easy enough to accomplish and turns out pretty darn cute. First, empty out the Nerds (we left one box full, just for a "surprise"). Print out little labels, 4 x1.5" with numbers 1 through 24 on them, and wrap around the boxes, securing with tape. Stuff the boxes with little toys, tiny scrolled messages, coins, chocolates, etc and tape the flaps shut.
Now to make the holder: you can use pretty much any method you'd like, but basically wrap the cardstock around the boxes so that it covers 3 sides, leaving one edge facing out so you can see the number on the label and mark that measurement. Cut a strip that width using the entire length of your posterboard. Using glue stick, cover the posterboard with wrapping paper and let dry.
Use the same method you would use to wrap a present to create the bottom of the box and tape/hot glue into place.
Place small boxes in holder and fold down the excess at top to mark then cut slits so the top can be folded over flat, with the excess covering most of the boxes on top to keep them in place.
At this point, I reinforced the whole thing with packing tape, which you really could do after letting the glue dry.
Then, I used a needle to create an embroidery-floss loop for hanging at the top and I used the holiday embellishment from the treats we bought to fill the boxes to decorate the front. Voila! Total cost: about 5 bucks. Time: about an hour, including coming up with all the cute little things to stuff the box with. Let me know if you want to make one of your own and need clarification! :-)
