Nose Problems

I purchased a silicone nose from a crafter, and it's of depressingly low quality. Worse still, even though the crafter states that their noses come with a felt backing (which seems to be a common thing included from most crafters) - my nose has no backing at all. The nose is just basically a chunk of silicone.

Since it doesn't have a backing, I have no idea how to install it into my project (which is essentially a plushie head, not a foam/resin/etc head/base). I don't know how to work with silicone @_@;

Does anyone have any advice on how I should install it? Just slather the back with glue and stick it on? What kind of glue would be best?

Thank you for any advice :}
