An even better way to do them is to bend at the waist, let your arm with the dumbell hang down to the floor, then without allowing your elbow to move (some people brace their upper arm against their thigh to prevent movement) raise the dumbell to your opposite shoulder (as you said, like your arm were in a sling). Slowly lower the weight without allowing your elbow to move, and raise again, etc. You can also do it seated with your upper body hunched over.
