Biggs Quilt - Block 4

I have finished block 4 of the Just Takes 2 Benjamin Biggs Quilt. One more block and there will be enough for 1 row of this quilt. I need to give some serious thought to backing and quilting as I want to quilt this in sections either by hand or on my home sewing machine. This block wasn't nearly as tedious as was block 3. I'm enjoying the variety in the blocks. They're not all the same level of difficulty.
