I'm at a bit of a loss, but I feel like I can't surely be the only person with this issue. We have a number of keepsake / decorative items that need to be hung by a hook. An example is a surprisingly heavy ceramic wedding horseshoe with a ribbon to hang it.
Because the wall is old plaster and masonry I can't use nails or standard picture hooks. I've looked at normal decorative hooks but they all have small diameter and/or short threads which simply aren't going to screw neatly into any plugs.
So, what on Earth can I use? I'm sure I'm missing a simple and obvious solution. For hanging pictures I've been drilling a hole into the mortar, adding a plug and then fixing a screw to hang in the picture. This works fine where you can't see anything, but I'm looking for a more attractive solution.
