This instructable is simply a way for me to note the differences between what the original instructable suggested and what I actually did. Also, I hope it will show that their instructable does really turn out very nice..
Step 1: I used single sheets folded over
Step 2: Gluing the pages together
Step 3: Trimming excess glue from spine fabric
Step 4: Creating cover boards
Step 5: Finishing cover boards and spine
Make sure the glue is VERY thin. Notice the first picture of the completed cover? See the glue streaks that seeped through. After seeing that, I made sure I used much less glue on the other side.
Step 6: Gluing the pages and lining onto the cover
I used standard construction paper for the lining. I cut it to size and folded it in half. I glued one side onto the paper first. When that dried, I glued the other side to the cover board.
I inserted four blank sheets of paper into the book before and after the first and last pages just in case any glue seeped through. Then, I let it sit under a nice stack of books for an hour or so to make sure the lining and spine fabric glue sets really well.
Step 7: Completed book
I also uploaded a video to YouTube that shows the completed book. It is located here.
