In this I will show you how to create a driftwood bookshelf. You do not need many materials and most of them are pretty cheap and the major one is free depending on where you live. You will need to find out if it is legal to take driftwood from the beaches in your state not all states allow this to happen, but some of them do.
You will need:
Driftwood quantity depends on the design you are going for.
Twine I purchased mine from Wal-Mart.
Glass for the shelving I purchased mine at home depot.
Some type of anchor to secure it to you wall(just in case it does not end up all that stable)

Step 1: Get Your Driftwood

This step is very easy it can take some time though, but who doesn't enjoy a walk on the beach anyways?

Step 2: Assembly of the Front and Back

All you have to do here is measure how tall and wide you want the shelves to be and cut the driftwood to the desired length. After you have done that you take your twine and secure the pieces together.

Step 3: The Skeleton

Here you are creating the "skeleton" of the bookshelf by figuring out how deep you want your bookshelf to be and cutting out the pieces then taking your twine and securing the front of the bookshelf to the back of the bookshelf.
