I did all that Monday when I returned home from DC. I also changed out the summer mantle to early autumn garb. I don't know when or why I started on that, but I find it a cherished tradition now that I look forward to. Since changing my living room decor to blue and yellow, Autumn has been more of a challenge. I think I met the challenge with a vintage Fall picture in soft yellow and blues with a touch of light brown. You'll have to let me know what you think about it.
I find something about changing out the mantle very soothing. I wipe it down with Murphy's oil soap, store the old season away until next year and fuss, stage, move, re-arrange, and tweak until I have it just right.
I used to tease my mother about her need to match everything, including the candy in our living room dish which was blue to match the room. I am more free-form about matching, but please note that my Indian corn is in yellow and blue tones which is probably a step too far into preciousness. Very twee.
