Lamp shade. Repair or replace?

I like the shape of the shade, but hate replacing fabric on one.  Glue and I argue.

But still,  can this lampshade be fixed or is replacing the fabric the better option?

There are also a few stains that are proving difficult.  

My vote would be to replace the fabric, the repairs would be too visible unless you wish to deliberately turn the repair/patch into an artistic feature/pattern on the lampshade?

If you decide to replace the shade, an iron on fusible lining may make the fabric easier to manipulate around the wires.

My one an only attempt to replace a lampshade ended up with ugly globs of glue on the inside and stuck together fingers.

I alternated between using fabric glue for quilting and a glue gun - the latter was awkward in the confined space inside the lampshade.

Is decopage an option? Or, painting (after simply gluing the bits back together)? I've not ever redone a lampshade the way it was originally done.

We would cut flowers out of tissue paper and glue them all over it, including across the rip.

One of the customers at the fabric store I worked at restored antique lamps for her shop. I don't know the methods she used, but she would cut the pieces on bias.

I don't use glue. I stitch my replacement shades. I usually allow a little bit of gathering so that I don't have to be perfect. A bit of trim sewn on also helps.
