Winter cushions

Still in the Christmas gifts, this is the present I made for my mother. It's a set of three covers for cushions. They are for the winter/Christmas season, because of the print on the fabric: a brown printed with white and blue trees ans Season greetings cotton from HobbyLobby.
The other fabric is a blue dupioni silk from fabric.com
The pictures colors are not the real ones because of the lack of light.

And I made the buttons with some brown oven-bake clay (Bake shop). It was my first try with clay, but I'm happy with the result.

I'm not sure I will ever try to do my own buttons since those are finally kind of sticky.
Does anybody know a way to avoid that?
