6 yards of tulle (I got mine at Walmart for $.97 a yard)
20 in. of 1/2 in. elastic
needle and thread (or a sewing machine)
To start, I cut my 6 yards of tulle into 1 yard pieces, you can have the fabric cutter person at the store do this for you.
I've searched for the perfect tutu tutorial and made a few tutu's using different techniques. This way worked the best for me. Here are some of the tutorials I used.
