For readers who also sew, or who just admire great clothes, Daniel Beaudet, who created the grey flannel dress for Kate in the fall issue, has posted further insights into his process on his blog.  It looks like Daniel, taking inspiration from our designers, may make the pattern available through his website soon: go hound him to spur him on.  The post is worth looking if only for his beautiful sketch of the dress in jade green.
