Yeah, they won’t fit under a 1×6 arch. That is fake news. I realized after I wrote it that I was thinking of a smaller curved slope, but I was heading out the door and did not have time to correct it. Full disclosure: the bag says “Greg 24” not just “24” and its written in red Sharpie, not green … and I counted twenty-EIGHT 1×4 curved slopes in the bag. 🙂
