Mending spoiled canvases

I began painting this canvas back in August but it wasn't until late September that I finished it. Actually, I spoiled it(I didn't mean to, of course). Let me tell you how I mended it.

What I used: Purified linseed oil, Oil paints, cotton buds,
and paint brushes

First I painted a beige background(I don't know why it doesn't
look beige in the picture), then I made this deep maroon dot
in the center of the canvas, and surrounded it by  these
maroon dots(I made the dots with the cotton
buds)

Then I surrounded the maroon dots with a circle of red dots.

I skipped a layer right here: now for the orange dots

The circle expands,more and more...






AND THEN............
A
DISASTER
happened!!!

The canvas got spoiled somehow...
...actually one of the dots smeared, and I was just correcting it when the paint smeared more and more and in the end it looked so unbearable...I had no idea what to do!!!!
apologies for not having a picture...
I took one but could not find it D:
(I EVEN searched the RECYCLE BIN!)

I finally decided that I HAD to do something about it. So I found
a rough half A4 size paper(actually an old solved past paper XD)
I painted over it with linseed oil using a paintbrush. I then took this
HUGE risk: I put the paper on top of the canvas and smeared
it. I  then added some paint to form a gradient.  The results
you can see in the above picture.

Of course, I had to do all that with my
hands! Here's what my hands looked
like after I had finished with
perfecting the gradient

Fast forward: The canvas, drying out on the washing line.

My canvas, all done(it looks sort of greasy because I took this
picture when the canvas was wet, so) It doesn't look bad,
I suppose. I am glad.

I hope you guys enjoyed all this dramatizing! XD I enjoyed a lot while painting the canvas :D

Keep tuned on, and I'll be back soon Insha Allah for some tips for oil painting! :)
