From DIY Life:
When the corner of my favorite wooden picture frame broke apart during a move, I pondered the ways I could fix it elegantly, preferably with a thin and quick-setting adhesive.
Wood glue would be sloppy on the finely crafted joint and slow to set. In typical carpentry, a joint can be held together to dry with a bracket or brace. Obviously I didn’t want to drill holes into my frame. I imagined using clamps to hold it together, but worried the glue would squeeze out and mar the finish, and I didn’t have clamps that big.
