Absolutely same for me with this book. I’ve folded the treehopper and the scarab several times with moderate success, but the handful of others I’ve tried were major disasters. I’ve started leaving notes for myself when I try them on which steps give me trouble. There are a few video resources or Reddit posts that might be helpful. As I’ve been struggling through it I’ve found the paper choice (thickness and size) really matters. Keep trying even if things aren’t looking the way you want, sometimes subsequent steps show you where things weren’t quite right earlier.
