I'm assuming that since her book came out almost two years ago, she's received plenty of press coverage and regularly posts amazing new work to her blog, that you're probably already familiar with Sophie Blackall and her work - especially this project illustrating 'Missed Connections' from Craigslist.
If not, this is a treat. I adore Sophie's work and while pulling affordable art options for the bathroom piece, I remembered how fond I was of her and spent quite a bit of time browsing her Etsy store.
Here are some of her gems available for purchase - I feel like gifting these to everyone I know.
