Can you buy blank covers to cover Paperback's.

Just make a cover like you had to at school!

What are you reading that's so controversial the person on the plane next to you can't know?!

Hehe you reading norty books, OP?

You can buy plastic covers for paperback but i'm not sure solid coloured ones are available. Maybe you could just slip a piece of lightweight card in to cover the book cover.

[now wondering what books 11122aa is reading]

Buy some wrapping paper or brown paper and make a cover! Are you reading 50 Shades??

I'm also curious about what you're reading!

I agree with PP though, wrap it in wrapping paper like we did in school.

If I saw someone reading a book where the cover has been obviously covered I'd assume they were reading erotica.

Use the dust jacket off a different book?

what you reading op?

I'm guessing it's not War and Peace.

It's only for six countries. Just put the kindle app onto your phone.

print your own, some ideas here

What are you reading?

< misses point of thread >

A covered up book will scream "unsuitable reading"!

I also need to know what your reading! Hopes it's something naughty!

In all the concern over international terrorism, nobody has given a thought to EL James' book sales

Anyway OP, assuming it's just porn not the Anarchist's Cookbook, if it's just one or two books then you unleash your inner Valerie Singleton and cover them with wallpaper

If it's lots then you get the transparent plastic covers from Amazon and then cut a piece of plain coloured paper to fit and slot it inbetween book and cover. Possibly labelling it helpfully with
"Definitely Not Porn! Probably Jane Austen or something."

'Paperback's'? Really?
There are no apostrophes in plurals. Is your cover for a grammar book?

Norty books

Buy a cheap 2nd hand book and remove the cover and use that (glue etc). Then Debbie Shags Doncaster RFC will look like War and Peace.
