I sashed the blocks with 3.5 inch strips of Moda's Steel grey. If I make another of these quilts I may make the blocks 18.5 inches square so I don't have to sash but still have a good snuggle size quilt. On the back I took a length of light grey and fitted in a row of grey, black and dark blue scraps. My favorite kind of backing.
I have it all basted together and ready for quilting, which I will do next week, after my new work mate arrives. That's right, thanks to the awesome sale at the AQS quilt show this week, I bought myself a Janome 8900, but that's another post.
