Cut your cardboard to size, and lay it out on your fabric, pattern down.

To make it easy to apply glue to my cover fabric, and so less would ooze through I added a bit of water to it to thin it out.

paint the boards with glue and smooth the fabric over them, leaving space between the spine and covers for a hinge. I glued it fabric side down then flipped the whole thing to smooth wrinkles out.

A piece of leather cut from an UGLY old jacket. Sewed with heavy linen thread (won't degrade in leather) This is a much more attractive use for it! (and yes, my stitching is a bit uneven)

corner glued to case. I used binder clips around the edges to hold it down as it dried.

To get those cool bumps on the spine, cut thin strips of cardstock and glue to spine before attaching leather. Here you can see string I tied around each bump edge while the glue dried to define it.

Example of strips on book spine since I failed to document it (and so many other steps! Sorry, hopefully you can fill in the blanks) You can do this on top of the fabric, a separate piece isnt needed

I used a plush fleece and made a double thick case, first sewing the zipper to the corduroy, then unzipped the whole length and sewed the corduroy between the inner and outer fleece layers.

I attached two zipper pulls so If I wanted to charge it while closed, I'd close the zipper around the cord. Watch out for overheating if you leave it on in the case, the fleece likely blocks the fan

corduroy looks like ragged book pages. Love it!

When done, spray it with a scotchgard meant for fabric and leather. It should give protection from dirty finger marks and wear better than if left untreated

I attached small ribbons to the inner corners so when closed up it doesn't force against the zipper, less risk of it falling out or dinging edges if it stays immobile inside.

And here you have the finished book-themed laptop case! I've also thought of adding a leather belt to wrap around it as a 'close'
