Pretty much exactly what I was thinking of. Layout the colors across the rows, but when you go to sew it you will be sewing the blocks along the diagonal lines. If you try to figure out the layout by the diagonal lines it will drive you crazy!
After I layout, I number each of my blocks with a 1" alpha/number pinned on in the upper left corner out of seam allowance but so I can orient the blocks correctly. I use Alpha across and Numbers Down, so blocks are A1, B1, etc., if there is a K9 block I use dog fabric!
Here's my own less great grid and picture vs. scan. But it shows what I mean about the L block, I hope.
I think the big thing for me is that each I don't really need to worry about the L shaped fabrics other than where they place on the top. Then for each of the contrast colors (the +1) so long as I have the two rectangles they will layout correctly.
