My niece needed a tutu so I came to her rescue.
4 yds tulle
5/8 yd non-roll elastic
1 1/2 yds hand dyed gros grain
Use the natural crease in the tulle and stitch a casing for the elastic.
Insert your elastic and then stitch together the short ends of the tutu so you are making the circle complete, BUT leave the casing open because you have to put your ribbon through.
Insert your ribbon in the casing so the ribbon covers the elastic.
Tie a bow for prettiness. This also serves as a drawstring so that you can tighten it.
Trim to whatever length or leave long.
