I love these easy ideas from Better Homes and Gardens. Easy and still doable in the final days before Christmas!
1. Hanging holiday tree
2. Holiday art. For this, they suggest canvas but you know what else would work? Just cover the lids of shirt boxes.
3. Giftbox decor/centerpiece. These are so easy to make!
I made something similar to use as a centerpiece for a baby shower. In this case, just stack up the boxes and hot glue together.
