fix the sequins with superglue near the end of the flights..that,s all i did,you can put some clear nail varnish over them...a m8 of mine fixed a sequin on the head of one of his yb,s it went on to win a big race from peniquick up in the borders,that was amazing,so ,as i say i saw it working with my own eyes,worth a try,if you put gold sequins on a black or dark pigeon the flashing has to be seen to be believed...
