Marimekko, a Danish pattern house founded in 1951, is known best for their Unikko poppy flower design as well as their bright and graphic aesthetic.
I just found out that Chronicle Books released a Marimekko book, Marimekko: In Patterns, a collection of prints and patterns with behind-the-scenes photographs of the creative process, which I find terribly interesting. It's so fun to see something go from a rough idea or sketch to the finalize product as well as what gets tossed out or edited. (Psst, Chronicle Books has a 30% off sale and free shipping with code GETBOOKS!)
I made a wallpaper inspired by Marimekko and fall; I hope you like it!
