That quilt is En Provence, which was this year's winter mystery quilt. There's a thread in the Quilting Challenges section right here on the Quilting Board, which follows people's progress on the quilt. Some are still making it. You can buy the PDF pattern in the store section of her blog site (there's a whole bunch of tabs across the top of the blog page).
The mystery is free every year, starting in late October when Bonnie posts the fabric requirements. Then the first clue is released on Black Friday, and each week until New Years. It's great fun. Then after February, Bonnie removes the clues from the blog and offers the pattern for sale.
