My fireplace is a favorite part of my home even though I don't use it much
I'm Dreaming of a White Christmas
The question regarding a classic, cozy, vintage Christmas atmosphere: Whatever type of Christmas you are striving for, i.e. Currier and Ives, Victorian, childhood memories, etc., would include sights, smells and sound. For me the sight part would be a Christmas tree with lots of ornaments, garland with pine cones and red gingham bows and snow (something, however, I have no control over). For the smell part I put drops of pine oil on light bulbs for a pine scent because our Christmas tree is artificial and lighted spice scented candles. For the sound element, I like quiet while reading an advent devotional as well soft Christmas music. Although I am not much into Christmas baking anymore I think decorated Christmas cookies and gingerbread people would add a nice touch to a classic, cozy Christmas.
