Please iron it on your clothes with iron if there is glue on the back side.
AND PLRASE put a piece of cotton cloth on the goods to protect it.

Also you can sew a few simple stitches after the ironing if you can,it makes it more firmly and durable.
If there dont have glue,then please sew it on your clothes,i believe this is not difficult for smart of you.
