By this time I was so excited that I'd have a project done in a day, I forgot to take pics! So, I made a standard binding and used a measurement of 5x the diameter of the skirt and had about 12-15 inches left over. This part was super fast because instead of doing 2.5" strips, I did 2.75 and I just put a little cut on the end of the fabric and then RIIIIIIPED! Everything was super accurate and it took me 2 minutes to do it this way instead of 10. For the win!
(Now it's under the tree, all covered up with gifts. Oh, the irony!)
