I guess you can see why I suggested that action.

Firstly, I think the canvas is a loss as you've gone through to the weave in about a hundred little spots. Those little spots need protection from the oil paint.

The YouTube guy over does it as it's a tear not a void it doesn't need a patch just bridge gluing

if he did use a patch, it should have looked like one of these two options

The uneven extended fringe threads help reduce the telegraphing of the patch shape to the front.

That makes sense .

There was a case in one of the Velazquez's large paintings in the Cathedral of Seville. The thieves cut a piece out of a painting of Velazquez and took it to south America to sell. Even a piece of Velazquez is worth of a lot. The police found them and rescued the piece. It was then attached back to the painting and I watched carefully and did not notice anything attached or once cut out so conservation was done really well.
In this case there was a quite big hole and it was covered by professionals. So I suppose it can be done. That's why I started this thread > interesting points of views being written.

My canvas is quite good, it's 3x lead oil primed and I brought it from Florence from a very appreciated art supply store. They make their own canvases. Top oil painters in the world now use their canvases. I will make an experiment and try to fix it although it might not work what I plan to try. I then paint a pleinair sketch to it as those canvases I need the most. Usually those paintings are with very little value, mostly practices and enjoyment of pleinair or references to larger paintings so I think it's worth to fix and paint.

@Marc Big thank you for your answer!

Could you affix something to the back of the canvas, and then fill it in the front with some kind of acrylic paste medium? Like a molding paste, fiber paste or something similar? Sort of like patching drywall. Fill it in, smooth it out, and it might create a firmer skin over the holes? You could probably do a coat of gesso over the entire thing afterwards.

I've never tried this. Just an idea.

TK H-H, very good idea!
