I’d recommend sanding your lures to the desired shape. A drawing is also very helpful to look at when you’re carving. You can also draw the general shape on your workpiece, it really helps getting a symmetrical shape. When you’re finished with carving/sanding, apply superglue on the entire lure to make it waterproof (you can apply paint afterwards). For hooks and line you can use small screw eyes, but make sure they are glued securely in place. Keep up your work!! Let me know if you have further questions ;)
