I must admit, I'm not a huge fan of wine bags. Most of them are tacky and look like they have been re-gifted a time or two. I usually just add some greenery and a homemade tag, but here are some interesting options for your hostess.

My obsession with burlap continues. Just cut the width/height you want and glue to make a sleeve. (Just enough to cover the label,) I especially love the texture of the velvet ribbon.
Here's an original idea..a wine bottle vase. Just measure Kraft paper to the size you want, wrap it and fill top with greens. tie bow around body of bottle so as not to crinkle paper!
