I recently (earlier today) attempted to create a custom helmet by cutting off a Bat's wings and melting the ends so they would stick to a Dragon Knight Great Helm. Long story short, they fell off and the helmet could no longer fit on a minifig. Luckily I had another helmet on hand, and my Dragon Knight leader is no longer bald.
Anyway, could anyone tell me a better technique for sticing bat wings (or other objects like plumes and such) onto helmets they weren't supposed to be on?
Some folk we never forget
Some kind we never forgive
Haven’t seen the back of us yet
We’ll fight as long as we live
