So, unfortunately, it appears Bloglines has been ignoring my clippings, which means I can't tell you who makes the top sponge cloth (I can make out the "Lotta" but not the last name. Help!) or where I first saw it. But, I did buy a set of these Marimekko versions (there are two other cute patterns available: polka dots and cows) that I spotted today at my favorite Rochester, MN store, Counterpoint Home. *Update: Lotta Glave makes the sponges seen at top, which you can get here. And I spotted the photo over at How About Orange.
Also, they're not actually sponges, but sponge cloths. Apparently people love them. I can't wait to try mine out!
