Those sashing strips are not attached, just laid in place for the photo op.
The blocks that I had done before I stalled out do have sashings and cornerstones on two sides already. So when I go to join the blocks, that tedious job is out of the way. Blue for sashings and the red for cornerstones. I love the two, as while they are colour ... they seem to disappear in between the blocks, while creating that boundary. At least that's what I see on the design wall and hope after it's all together I think the same.
Although I am starting to wonder if the blue/red are right for the rusts/browns such as the Good Cheer block above?
DublB ... come on back and join me! Don't wait til next month .. and with that new machine you're really ready to roll!
