A note for odd sashings, I'm adding the right and bottom sashing to every block as I go, so I don't have to do a pile of piecing at the end. Week 2 includes H1 and I've just realised that all the blocks from column 1 can have the left side sashing added as well.
Sorry, I can't remember who decided to add their sashing as they went, but this is for you. :-)
