Although my design is a bit more complex than that of the other authors deemed most suitable for the use you'll give.

Step 1: Materials and Tools Needed

Materials:

A piece of corrugated cardboard 2 mm and 20 x 27 cm, I use the finest and compact I found, care is very important for the armed correct holster to the cardboard with the specified thickness, being thicker will to modify thebackground so that the pleats to do suit.
A piece of cardboard for covers of 20 x 30cm.
A cut of ecological leather (or any fabric or paper you like) 18 x 23 cm to line the 'container' of the kindle.
Another cut leather, cloth or paper of 22 x 32 cm for covering the lid.
30 cm of elastic to the closure of the lid.
A piece of fabric 15 x 20 cm to strengthen internal binding caps.
A cut paper or fabric 15 to the inner end 20 of the cover (optional).
Vinyl glue or other glue to cardboard.
Contact cement to glue the leather or fabric.
Instant glue (cyanoacrylate).
A neodymium magnet 5 x 5 mm and 2 mm thick, use a patch to remove a broken hard drive.
masking tape to hold the parts while the paste.
25 cm of a thin film that will stick to the container to remove the kindle inside this effortlessly.
A piece of EVA foam (also known as foamy) 3 x 20 cm (optional).

Tools:

Utility knife, cutter or other tool to cut cardboard and leather
rule
A surface on which to cut, I use a cutting board vegetable not want to break the workbench!
Metal ruler or other item to use as a guide to make the cuts on the cardboard
Do not use a plastic ruler that was damaged!
Scissors
Printer
marker

Cost: pretty low, in my case just buy the elastic and thin ribbon, cost me 50 cents, what long cardboard boxes, fabric reinforcement cover the take of an old shirt and was about to throw eco leather ecological leather was cut I stay upholster a chair.

Construction time: 3 to 4 hours.

Step 2: Preparation

Download and print the forms. As noticed mold container I kindle this mirror, this is so that we will all cuts on the side where the paper will stick to the board and this part stay on the inside.
To check the size of the printed plans is correct check that the width and height match the measures have included (in blue).

Paste the molds on the cardboard is not necessary to completely paste with a few drops of glue so that it will not move enough.

Step 3: Cut the Cardboard to the Container

Cut the perimeter of corrugated cardboard along the lines of the mold and using a metal ruler as a guide, align and firmly hold the guidewire while two or three firm strokes are made with the cutter. It's also a good idea to support the cutting guide on the cardboard will use and cut the cardboard on the side discard, this way if the cut deviates can correct and not have to start over. Do not forget to protect your desk!
Cut container folds areas, is necessary to pass the cutter carefully cutting only the top layer of corrugated cardboard, no more than 1mm deep. After cutting you have to remove the top layer of paper and carefully press the corrugated inside to crush him against the bottom, if it is peeled away the surface layer when there is no problem, just need the paper layer intact Fund.

Fold all edges of the container and ensure that fit properly in place, cut the excess cardboard to correct the shape if necessary.

Step 4: Line the Container

Mark and cut the leather to the measures set to get it ready to glue on cardboard
It is very important not paste all the leather directly on the cardboard, then this will cause that can not be folded.

First attach the top face contact with glue, when fully dry cut leather inside, where anger kindle screen, leaving about 1.3 cm margin at the narrowest part and 2cm at the widest part, this surplus was then stick inward angles are cut at 45 degrees leaving 1mm uncut in part to the nearest corner, once glue the flaps cut in, I also covered the corners with pieces of leather, but is not necessary because the inside of the container is not.

Fold the sides of the sides of the container and temporarily secure them with paper tape, display and adjust cutting leather anger stuck on each flap, leather pasting each tab one by one.

Finally fold the sides back of the container and glue the remaining leather, leave only 1cm leather on the back and leave the rest of the board in sight, this is the face that is then stuck to the lid.

Now paste a leather trim 0.7 x 2 cm to the top of the container where we introduce the reader once completed and one on the top giving access to the USB and the power button, not having this serious handle more complicated open covers.

Step 5: Cut the Cardboard Covers

Cutting the board in a plane, in this case are two lids, the 'back' and two small strips of 5 mm wide which will be very useful when armemos caps, these strips spaced ridge tops and allow open and folded back caps.
We must also realize the depth at the top to insert the magnet that we use for the kindle will automatically turn off when we close the lid. This draft is marked at the level of the caps as a red square to 2.5 cm from the left side and 1.5 cm from the bottom.

Step 6: Assembling the Cover

For this step we begin with what will be the spine of the book, I'll stick with contact cement, focusing on leather and hope it dries. Then just put the spacers glued with tape so we can remove them then, and last contact with glue stick caps on the leather, taking care to align correctly.
Once the glue has dried remove the separators, we present the magnet and paste with paper tape, also present on the cover the container with the kindle in and we make sure that when you close the lid is turned off properly, otherwise we will have to moving the magnet to a more appropriate position or find a more powerful magnet.

Presented checked everything and it is fully lined proceed to finish the top, stick the fabric on the inside and using spacers again to the fabric from sticking to the shell within the separation space left between the covers and the spine .

If the cardboard used to make very fine tapas is a good idea to reinforce the ends with cyanoacrylate glue the leather before.

Measure again 1.5 cm in leather flaps were and match, then check that the connections are well tip and glue in contact previously 1cm mark on the outline for not putting more glue. If the binding of leather flaps is slightly separated at the ends, slightly stretching solves the leather and sticking cyanoacrylate bonding edges joining leather care may get stuck !! fingers.

If joints leather inside of the lids were not as we wished we can cover them by cutting and pasting a box of paper or leather.

Step 7: Paste Each Part in Place

In this step we will stick with cyanoacrylate tape that was used to remove the kindle from its container, this tape is glued on the inside of the container, marked on the map as two green rectangles. Remember to do this before gluing the folds of the container, forget it and believe me it is much more difficult then.
Now we will stick inside the folds of container kindle, opening each and putting PVA glue, making sure we do not stay glued access cover USB charging. We all parties in its final position and ensure with paper tape until dry, once dry glue the elastic in the back of the container and paste this into its final position on the covers, taking care not to hit the caps to be where our readers go and where we will have access to USB charging and the power button. Remember to leave enough elastic strap that will stretch and then stay looser.

Enter again the kindle in his container, close the covers and check that fits snugly in place and does not move, if you move stick on the inner edges of the container EVA tape or other soft material.

If they wish they can put at the left top leather flap to keep papers, this tab is marked at the level of the tops with a dotted line, not the paste that is not useful to me.
