No, that isn't the name of this block but I'm thinking that it might need to be.
Set in seams. Tiny pieces. 4.5" block.
I sat down to cut the templates and paper-piecing patterns out and thought that this was going to be a fairly easy block; only 15 pieces. That was before I thought the piecing all the way through and realized that there were set in seams. Now, I've made an entire quilt, a tumbling blocks quilt, that was nothing but set in seams but those blocks were bigger!
I'm proud to say that I am pleased with the results even if there were a few times where I had to rip out a seam and start over.
P.S. The real name of this block is block E-4, "Buffalo Tree Hopper".
