Christmas wine stoppers

[lolitahaze1.livejournal.com]

I want to make wine stoppers for my (ex)mom-in-law for Christmas. I am not sure if I should use, rubber corks (for longevity) or classic cork corks. I do not drink any alcohol, so I do not know if the rubber will effect the taste of the wine. Also, where would I get rubber corks? For that matter, where would I get cork corks or any type of corks for wine bottles? Thanks.
