Lotta's portfolio site includes more than just patterns. She also has a nice variety of book designs and illustrations. You can order decorating shelf edging with Lotta's art from a Swedish site called Happy Store. They also sell mugs with her designs.
We came across Lotta's patterns on the {frolic!} blog.

The second pattern [bananas, et al.] is great, too!
Absolutely love these amazing patterns! I'm a fan of the black and white patterns and the blue and white patterns. They go so well together!
I googled this amazing designer half the day trying to find more... only a few references on a few other design blogs, her own website (incredible!) and a store that has sold out of everything. Does anyone know where I can buy her stuff online? Most of all I want wrapping papers in the fruity designs. Lovely, gorgeous, fun. That kitchen makes me swoon.
That... makes my head hurt!
Bad, bad room, I have to go lie down now... ;)
