I use nibbles on jigs. I like to cover the point and barb of the hook with them if it has a barb, otherwise just push them down next to the body of the jig if it's barbless. I use the kind with sparkles on the outside. Makes the jig look like a minnow losing its scales. I just jig the whole thing slowly up and down in the water, or drag it along behind at a speed that feels like I'm barely moving. Kind of creates trail of scent and 'loose scales' in the water.
