I discovered the beautiful tree and floral artworks by Karoline Rerrie at the online shop Howkapow, although having first seen her work in the masquerade postcard book. Karoline is an illustrator and screen printer based in Birmingham, UK. She creates screen prints and greetings cards which are sold in art galleries and exhibitions all over the country. You can find Karoline's blog online here or google for a gallery/shop near you.
