Step 4Make some more holes (in your cover)!
iImage Information

You're insides are ready to be assembled but you still need to make holes in your cover. To place these holes properly, remove the top and bottom sheets from your stack of insides. Place the bottom sheet so that the holes you've made in it are over the folded over 1/2" you made during prep and so that the rest of the sheet lies just how you want it to when the whole thing's assembled. Take you hole punch and press it into the holes hard enough so that it leaves a mark on the cover material. Do not use your hammer, you'll just make a hole. Repeat with the top cover and top sheet.
Now that your holes are marked, unfold the 1/2" flaps on your covers, place the hole punch over the marks and lightly tap it with your hammer until you've made a hole.
