The slip-in hooks are described below in the order of my preference.
The most expensive set was $3.99 at Bed Bath & Beyond for 14 Slip-In Hooks...
...and it was the easiest to shape into a good-looking stand for a painted rock.

The medium-priced set was $2.49 at Hobby Lobby for 14 Pleater Hooks. (Four hooks were end hooks and could not be used as stands.)

The lowest-priced set was $1.97 at Lowe's for 14 Slip-In Curtain Hooks.
The metal was thicker and harder to bend (even with pliers) and it was difficult to shape the hook into an acceptable-looking stand.
