I am tempted to give this a go using my BOM fabrics.
Wouldn't you start like a log cabin block? I've made it in paper. Start as you would for a log cabin, but add an additional black log (4 1/2" x 2 1/2") next to the patterned one. Then add a 6 1/2" by 2 1/2" log in a different pattern at the bottom.
In my pic, the red is in place of the black.
So you would make four of these in different colours and on the fourth, the longest piece would be yellow and go to the left of this one.
Clear as mud.
