These are my two test boxes, since I wasn't positive that the measurements were perfect. Good thing, too, because they're definitely not perfect. The first box was made out of my yellow-green and gold vine paper.
There were problems with the hinge, so the lid of the box is a little too high at the hinge and juts out over the front. See?
Not to worry, though. I fixed that problem with my second box, so the hinge is the perfect size.
You can see that the lid isn't raised at the hinge, everything is flush (although the box is open a bit in the picture). The only problem with this one is that in the back, the spine is about 1/16" short. You can see that in the bottom left-hand corner of the picture. Hardly noticeable, but still there. The next one will be perfect.
Even when they're not perfect, I get so much satisfaction out of making something with my hands and seeing the finished product. And just the four boxes I've made show so much improvement.
