>>but thought I might share that I have struggled with the blocks, especially the second one. Watched the video multiple times to try to get placement right.<<
sb1959: you are in good company here! LOL For me, the second block was tricky, especially when I got to adding the circle. The instructions and videos are really great, but still have trouble when I assemble the two diamond/wedge units. One of my outer points (same issue with the first block) is off and so it makes adding the circle a challenge.
