Tumbling Blocks with no Y seams

Our guild had a workshop yesterday after our meeting. We learned how to make the blocks shown in this photo. These 8 blocks have not been sewn together yet - I want to wait on that until I have made more of them. It has been challenging to find fabrics that blend together and ones that have 3 in light, medium and dark values in each color. The pattern calls for making a quilt that is about 47" x 58," so I have 56 more blocks to add to these 8. The setting triangles would only be at top and bottom of the design. I probably won't be adding more to these until after Christmas since it seems that I keep on adding project to my list of things to finish by then!
