Step 1: What You Will Need....
A wooden dowel (I found one in my mom's closet full o tools and things)
Duct tape (Very easy stuff to find)
Surveyors tape but preferably something stronger. (Mine was $2. You can get it at someplace like Ace. It isn't sticky, it's just for things like tieing on stakes to outline something on the ground like where a house will go. You could also use other things instead.)
Step 2: Take the Tape And....
So cut all the peices of surveyors tape you need and then tear off a piece of duct tape as long a your dowel. Put it on one end and take a piece of surveyors tape and loop it over the dowel and tape it down. Keep doing this until you have put as many loops on it as you want it to have. Put them close together without too much of a gap between them.
Step 3: Smashed Mutant Octopus
If you find that it still doesn't look like it will stay on put some very thin pieces of tape between each of the loops to hold everything on a little bit better.
Step 4: Almost Done!!
Step 5: Bam!
Enjoy your smashed mutant octopus bookshelf! If you have any questions just ask :D
Step 6: Individual Book Holder
So take what ever you're using, (surveyors tape, caution tape, cloth, etc.) and if it might rip because of the thumbtacks/nails you should put duct tape on the end. Put the ends together and put a thumbtack (I wouln't suggest thumbtacks) through the ends and hang it on the wall. There you have it! Put books in it just like you would the other one.
