Pom pom flowers made from variegated or space dyed fall-color yarn with natural branch stems look great right now. And you can do something just a bit different and tie the branches together with some gold ribbon as a fun element on your fall table.
Okay, it's not exactly fall yet in most of the world, and I have to say, I prefer a gentle transition from the brights of summer to the rich colors of fall, which is what I've tried to do in this photo. My eye really isn't ready for the deep burgandy and reds that we generally associate with Rosh HaShana here is Israel, and certainly not for the orange/brown black palatte seen across the United States.
I'd say start gathering some items from around your home, touches of wood, some metallic gold, and mix them with some brights here and there. Nothing drastic, just a slight soothing change in the colors we choose to use on our tables and around our homes.
And if you haven't yet discovered the joy of pom pom flowers (which you can always pull out at a moment's notice to make a festive centerpiece) I highly suggest that you make some! Stored in a dust free spot, they'll last for years and are so much fun, believe me! See my post from last year for more information regarding pom pom flowers. Perfect any time of year, just switch the yarn colors to suit the season. Metallic gold and silver ones would be great too! And while you're at it, make a bunch so you can lend some to the neighbors when they need a festive centerpiece in a pinch- as I always say, nothing beats using our crafting skills to do acts of kindness!
