I think the sashing strips give the blocks a little bit of space. I don't have enough of a single green, so I'll have to mix is a bit of the slightly darker green that you see on the outer edge. The inner bits are 1.5 inches and the wider outer part is 2 inches, so it isn't much, but I think it makes a big difference in the look of the quilt. Kurt has taken the children off to the Art Festival and I elected to stay home alone. It is the first chance I've had to sit quietly all weekend and I am relishing it.
