I was browsing Amazon a few days ago and spotted some amazing deals on a few excellent crochet books to download to Kindle. You don't need a kindle to access them, I use the Kindle app on my smartphone to read them.
Here are the links to the books. All are well worth their current price!
Crochet One Skien Wonders - £1.99
I'm not sure how long these books will be available at these prices so be quick if you like the look of one.
