Wine-cork poppers should look like natural fish food when completed: eyes, legs, body. Put it in a bowl of water to test your pattern and assess its action before taking it out for a test drive. Does it float? Does it look froggy or buggy enough? Good. Now get out there and catch something. Bass and bluegills are the primary target species for wine-cork poppers, but crappies, perch, pike, and even redfish will hit them.
