My daughter sent me a pin from Pinterest for this little doodad. I’m not sure of its official name. But, it does a great job of holding the pages open while reading a book. Despite Kindle et al, real paper books are still with us. It’s a bit irritating at times to have to use both hands to hold the pages down.
This one is walnut and finished with beeswax and mineral oil.
The challenge is to drill and finish the hole from both sides, then change the axis finish the remainder of the piece.
