Use the sticky type of silicon that is generally sold for bathroom grouting. The type that you can scarcely remove from your fingers if you happen to touch it.
Here I am putting a long running pad of silicon on the bottom of a 'hand of Fatima' that I wish to use on my kitchen counter as a spoon rest.
I've squeezed out a line of the sticky stuff on the back.
Now I will shape it with my finger using a small bowl of liquid soap. I used laundry soap but you can use dish soap or shampoo. You can cut it with a bit of water if you wish. You don't need much.
Dipping my finger into the soap I shape the silicon to lay flat. It won't stick to your fingers.
Make dots of silicon to form round buttons instead of long lines of you wish.
Let it harden and wash the soap off. Now you won't scratch the counter. Sometimes, after continual use especially in a wet environmental it will eventually listen off and you may have to pull it all off and repeat the process; but it will last a good long time.
