Tie in Fold Over Eye Tabs are perfectly clear tabs to which 3D Adhesive Eyes or 3D Big Fish Eyes are attached. They will adhere without the use of any additional glue. You can tie in before tying your fly or cut and tie in after the fly is finished. Small works with 1/4" or smaller eyes, Medium 1/2" or smaller eyes, and Large 3/4" or smaller eyes. We like to add these before or after tying the fly; in either case, folding them over with a UV cure glue will add even more strength.
