Maija Louekari is a Finnish designer that has a great collection of both illustration and textile design in her portfolio.
Combining lovely colors, line illustration, and bold shapes, her work is amazing. She also has a whole set of textile work for sale over at Marimekko (no online store), a “leading Finnish textile and clothing design company that was established in 1951.”
You can see more over at Marimekko or check out her Portfolio, which is great. You can also see a lovely collection of her work featured at GrainEdit, one of my favorite design sites.
