48in diameter, advanced beginner. This Christmas tree skirt is perfect for the non-traditionalist. Made with bright, saturated fabrics, it is both modern and whimsical. I especially love the idea of using this beneath a small children’s only tree, filled with colored lights, reflective glass ornaments and piles of cheerful presents beneath. The unique hexagon shape will have everyone asking where you got it. And as a bonus, this project was designed with 10in x 10in squares in mind. So it is a great project for some of the precuts you might have stashed away.
