This is "I-9 Chase a Myth", an advanced-level paper-pieced block. Although last night I wasn't looking forward to tearing out all 41 (not 42 as I previously mentioned) pieces of paper on the back, it turned out to be a myth that it would take long. Using a small stitch helps quite a bit with the removal. However, the smaller stitching can make it a pain if you need to remove stitches, so be careful as you go. On this block, there was no need to match seams when I had to sew the two outer triangle sections onto the larger middle section, so my chances of having to tear out stitching were fairly low.
