I love the tree collar trend for Christmas trees, and while I didn't buy one this year, I might have to look for one on clearance after the holidays! This 27" grey Aubrey handwoven tree collar at Pottery Barn was originally $149 full price, while this 26" Wondershop split willow tree collar is priced at just $40! Either would look so lovely with your farmhouse, coastal or transitional decor.
