I love when the temperatures start to cool down! We don't have a change in colors, but anything lower than 90 degrees feel good. I start decorating for fall the day after labor day!
I especially like decorating trees. I think I have a tree for every holiday except Valentine's Day. I collect HMH red plastic cookie cutters from the fifties like the ones my grandmother used when she made sugar cookies. A few years ago I went to the Antique Show in Roundtop and found some orange cookie cutters with halloween figures. I use those and a few other ornaments to decorate a small black tree. This year, I bought a bow to put on top of the tree. The bow it a little big and overpowering, but I still like the colors.
I found a rickety, orange chair a few years back to use for halloween decor. I put an old suitcase on top of the chair and added a candy bucket, black speckled colander and a pumpkin muffin tin on top.
