I'm planning on sewing my blocks together without sashing, the way they look in my photos. The link to the blog shows them sewn with a white sashing... very pretty too. And you can do them with sashing on two adjoining sides and make a "Dancing 9 Patch", like this:

(Ours would be even cuter because they are little checkerboards, not random)
This way is called "Ric Rac Nines":

There's also "Nine Patch and Snowball". I'm sure we'll think of others. Save your leftover short strips for an awesome piano key border.
