I just absolutely love creating my own folded book art. It's such a fun way of re-using old books and give them another purpose.
I've searched and searched the web to find any tutorials on how to do it and i just couldn't find anything. Untill one day i found a website called foldedbookart.com (THEY NOW OFFER A 25% DISCOUNT ON ALL PATTERNS FOR THE FIRST 100 USERS. USE COUPON CODE: INSTRUCTABLES25) which offers already made and custom patterns.
On of the patterns they used to have was this little heart sign. For me this was a real good way to get started as it's quite a quick pattern to do and the result still looks great.
In the next steps i'll explain to you how to fold this heart into a book. (I used a picture from their website for the front image)
Completing this tutorial can be done within 45 minutes.
