The Courthouse block is similar to sew as the Log Cabin block. It is a bit easier because you can add 2 strips to the block center before having to press and square up the block. I have cut my strips at 2" wide which will give me a finished block size of 10.5" square. Here are the size strips you will need.
Yellow: 2 - 2" squares, 2 - 5" x 2" strips, 2 - 8" x 2" strips
Black: 1 - 2" square
Green: 2 - 5" x 2" rectangles
Blue: 2 - 8" x 2" rectangles
Black Print: 2 - 11" x 2" rectangles
In the photo below you can see the layout of the strips and the center 3 squares have been sewn together. Press the seam allowances toward the outside of the block for all steps in the construction of this block.
Sew the 2 green 5" x 2" rectangles to both of the long sides of the center unit. Press seam allowances.
Continue sewing strips to the center unit in an alternating manner, pressing, and squaring up center unit if necessary.
So it's kind of important to get the layout right in the beginning. Here you can see that I messed up on the layout and got all the way through the block before realizing what I had done! LOL!
