The leader at my Angels Quilting group (associated with Chaplains office at a local hospital) gave each of us a bag of fabric and said it was a Challenge to work on for next months sewing day. I used the Missouri Star Quilt Co Bowtie to use up as many as possible of the 2.5 inch squares I was given. Each block is approx 4.5 in in size. Good way to try this pattern and it was easy. Plus they have a youtube tutorial as well.
