Hi All

i plan for my new SFS piece to added temple flaps. see pic below

To wearer use flaps, could you tell me if it more difficult to glued the lace on side ? Can i use SFS lace for the Flaps ?
The attachement flaps with glue is secure, does it need special attention ?
I afraid if a flap is detach, and i don't see it...
Which glue can i use, ultra hold ?
Any advices are welcome.
