I am no expert on this....just listened to a lady explaining & demo-ing it and had a play at home. This is really about the use of salt - not to explain anything about dyeing fabric.
I grabbed a bit of white fabric and washed/rinsed it in dishwashing liquid....because it was handy...use normal laundry liquid if you prefer - it's just to remove whatever is on the fabric. Leave it wet.
Make up some coloured solution - Use dye if you have it - I used acrylic paint and added a drop of blue food colouring. If you use acrylic paint - you may need to stir it very thoroughly or - as suggested by the lady demo-ing it - strain it - to remove any blobs of paint.
Soak the fabric in the solution. Leave for as long as you need to to get the colour you want. Remove - squeeze out the excess liquid and lay out - I put mine on baking (parchment) paper.

Now the fun part.
Sprinkle salt over the fabric....
I used Rock salt on the bottom area - ground rock salt on the top area
You can also use cooking salt, or Epsom salts. I am sure salt flakes would be interesting too - I was just using what I had in my pantry for my test piece...but might buy some salt flakes for another time. I also added Bicarb of Soda on the top...I wonder if it made a difference?
Because the salt draws in the colour - you get bigger "bubbles" from the rock salt than from table or cooking salt. (Hence thinking that flakes would be good.)
Here is the side I put the salt on
