you can use a contact cement and apply it with a toothpick sparingly so you don't get it on the hair.

try this website and search for bunny strip flies  It has a decent looking streamer pattern recipe and step by step instructions

I have tied it in place with thread and used super glue to hold in place before also but only on  top not both sides. I think I'll try the streamer myself

good luck

 I use a clear drying latex cement called VAL A Tearmender for gluing rabbit hides together for my Double Bunny pike fly. you can also  use it to glue down wing cases.
