Final books for the moment for my treasure chest of spiral books. Laser engraved spirals on wood from old window blinds.
A palmleaf slat style book, a corner post book, and a Jacob's ladder style book (mechanics are a bit balky due to material thicknesses, but this is my first. Thanks to Karen Hanmer's excellent online instructions). The chest is now full, and time to move on, but this has kept me happily occupied for months.
