Melissa, I think GUEST means to use the side of your finger by keeping your fingers parallel to the strings with your palm facing you, fingers pointing to the bridge. Then you would turn your hand to use the fingertips (palm facing neck of bridge, fingers pointing away from you)for faster picking of multiple strings.

Don't know what kind of tape my friend uses (I'll try emailing him, he lives in the next state) but it's pink and stretches. He winds it around the fingers a couple of times and it protects his fingers amazingly well, clinging enough to give him sensitivity but strong enough to cover the open blisters.
