Here is the finished product:
Step 1: Cut your paper. My book shown is a 4x4 square so the paper needs to be 32x4. You could make it any size square, and just multiply the finished size by 8 to get how large to cut the paper. (So a 5x5 square would be 40x5)
Step 2: Make folds on each 4" mark (or 5" mark if you are making a 5x5...) Below is an image of all the folds we will make, on one side of the book.
Step 3: From here on out, I will show you how to fold one half, you just repeat for the other side. Fold the corner down to the edge, making a triangle.
Step 4: Now on the second square from the middle, fold it down to the side, making another triangle. What you have now kinda looks like a pyramid.
Step 5:Fold the pyramid back towards you, overlapping the first square.
Step 6:Now fold the last square (which is now a triangle) and the 3rd square around the back.
Step 7:You should now have something that looks like this:
Step 8: Tuck the triangle under the flap made by the other folded triangle.
Step 9: And now repeat for other side.
Since I know that the pictures and description may be a bit confusing, here is a video of me folding half of the book. Happy creating!!
