I went to Joann Fabrics and bought this glittered tulle. I got 2 yards, just to be sure I had enough. I think it was $5.99/yd, but I had a 40% off coupon so I got it for a good price.
I cut the tulle in half lenthwise, then cut it in half lengthwise again so I had 4 long, narrow strips.
The ribbon (leftover from my wedding decorations) is the waistband. I basted a long strip of the fabric and gathered it so it was the length of the ribbon. Then I pinned it down to the bottom half of the ribbon to hold it in place. I did this for a total of 3 layers of tulle.
Once I had all 3 layers pinned to the ribbon, I zigzag stitched them down on the sewing machine. To make the waistband look nicer, I folded the top half of the ribbon over the seam of the tulle and straight stitched it down.
This is what I ended up with, although it's not the finished product. I won't show you the finished product until Halloween! I added strips of ribbon to the ends of the tutu so it can be tied on, and I trimmed quite a bit of length off the bottom of the tutu. It's so cute!
And now I have glitter all over my house.
