I am making some fabric ceiling panels. The panels are wooden stretchers with fabric stapled to them, similar to a painting canvas.
The panels will be flush mounted with trim boards that border them. The panels are different sizes, but about 4' x 6' or so. The problem is how to mount them so that they can be removed if needed to access various utilities in the ceiling.
It is not possible to shift the panels side to side, because they are hard up against the trim boards. Also, they cannot be pushed upwards because there are joists right above them.
So, one idea is to use magnets and another is some kind of spear and socket connector, kind of like a speaker cover. Both of these approaches have the disadvantage that it will be difficult to pry the panels out, because there is no gap between the edge of the panels and the trim board.
