Practised transparency with watercolour and pen.
It is hard to find books on the internet with felted illustrations, and even harder to find in stores.
There are not enough felted illustration books out there!
Very few I have found. But what ones I have, I feel inspired to pursue my passion to create felted illustrations for books! (and very inspired to buy them all!)
The latest discovery is Cosy Classics, a few classic stories illustrated with felt! (I have bought Pride and Prejudice)
Some more doodles of a book I like.
The Christmas Truce - Carol Ann Duffy, illustrated by David Roberts.
