OK, that may be hyperbolic, but I made these using this tutorial and just get such a crazy sense of satisfaction from them! They fit pencils perfectly, as you might expect, though not, alas, the bigger pens that I like to keep in my bag. Still, though, they're cereal boxes!
The one on the right was made within 20 minutes of seeing the posting when it first went up -- I looked, I printed, I stood up, I made one. The one on the left was a project done on Thursday night when I was trying not to fall asleep before my bedtime. They were originally cereal boxes, as in the link, but before cutting out the template I used Modge Podge to affix some scrapbook paper to the cardboard.
I also put two coats of Modge Podge on top of the paper, one before cutting and one after it was all assembled (let everything dry before proceeding). I decided to give this new one to the mother of two friends of Ellie's who had Ellie over yesterday and sent us home with all kinds of new clothes to boot! (Her daughter is in the next size up of clothing from Ellie). It was like Christmas! So I added a little note inside the top cover:
It was a good way to bring Earth Day to a close...I"ve had the scrapbooking paper since Ellie was 18 months old, so I'm so happy finally to have a compelling use for it!
