Monochrome color scheme always works. You can find pheasant feathers online.
This is a perennial favorite. Runner in the middle and pile pumpkins in the middle, mix some candles in and antlers. Btw, pet stores sell antlers, you’d just have to spray paint them if you want white or gold.
This couldn’t be easier, just add a garland down in the middle, pop some votives around it and you’re done! Oranges, tangerines or pomegranates or even apples and pears would be great dotted on the garland.
And last but not least, some ideas for kiddie tables. I’ve used brown craft paper and taped it to the table and added some crayons for kids to color also. Meaningful Mama has a great idea to have kids write down what they are thankful for.
