By the time you read this review, the Kickstarter campaign for How to Think When You Draw Vol 5 has already ended.
How to Think When You Draw series of books are packed with quick tips and drawing techniques from The Etherington Brothers. These books are always launched with Kickstarter campaigns and they are always sold out. Each time a new volume is out, there are reprints for previous volumes. The only way to get the books is through the Kickstarter campaigns so if you want to get these books, I recommend you follow The Etherington Brothers on their blog, Twitter and Instagram pages.
While you wait for the next volume, head over to their Instagram pages to check out the tips and techniques they have already shared online.
Below are selected pages from volume 5.
There's also this foldout card with an index on all the subjects ever featured across the 5 volumes.
