Super small little notes on how I do my eyeblanks because I always have issues with them coming lose
1. Serrate the back of the eyeblanks by cutting Xs into them with a craft knife
2. Glue the mesh down
3. Put the mesh down and press firmly
4. Glue over the back of the eye mesh to double reinforce
5. Trace the eyeblank shape onto adhesive felt and cut out.
6. Press the adhesive felt cut out onto the back of the eyes
Cut out the eye blank and wala!
