Tree skirt

I decided to make a tree skirt as my next sewing project.  I wanted to have it done before this weekend so I could be ready for the decorating. 

What do you think?  I think it looks pretty good.  I didn't want to buy a pattern.  (The are pretty expensive so the hardest part was getting it in my mind how to sew it all together and cutting the semi circles.)  My mom drew me a picture and Matt helped me in make the semi circles.  Thanks for the help Mom and Matt!
