This is the layout I thought I wanted to use, zig zags superimposed over a stripe background, but as I put the last 16 blocks up I realized it won't work. Look closely at the lower end of the light color peaks and you will see that the seams don't line up.
When blocks are lined up like this, everything is fine.
But when the blocks are like this, the seams don't match up. The only way to make it match would be to trim the 2 edges with the long stripe, on every block and I think that would throw off the balance of the block.
So......I'm back at the design wall. Here are the stacked spools again, all 48 blocks.
On this one the second and fourth rows of spools are turned a quarter turn.
This one is every other spool horizontal/vertical. I like this layout as well as the stacked spools, and of course I like the original Twisted Rail. I don't think I will have any new snow to shovel today so maybe I'll get the blocks sewn into a top.
