When the spun fiberglass breaks down they become unstable and collapse. This is largely due to the fact that these shades have very little framing.
This lamp shade we acquired from Frank was in sad shape (no fault of Franks). I thought I would take a stab at fixing it with the tried and true method I used before on other shades. This repair method will never make it look as good as when it was manufactured but it will look a lot better than an unraveling mess they can become. Overall I am happy with the way it turned out.
Here are the tools needed to repair this shade. You will need to mix equal parts glue with equal parts of water.
I use clamps and long pieces of wood to hang the shade on to help keep its shape when applying glue.
Once the pieces of wood are spaced right it helps it keep its shape.
Once the glue is applied use a blow dryer to help the drying time. Try to hang it in a way that lets it keep its shape. I had to hang it upside down to help it keep its form.
Here it is after glue has dried.
Here it is at home atop our new Moss lamp. I think it looks good!
