Block 3 is called The Stairway and is made our of squares and rectangle shapes. Cutting out all the shapes was easy. I'm hoping when I sew them together they all line up good.

My color choices for this block are shown below, which happen to be the same color patterns that were used in the sample quilt. You only needed 5 different colors, (1) reds, (1) orange, (1) blue, (1) yellow and (1) green.
