Gather your materials. I used: tulle(not quite sure how much I had...didn't need too much considering the size of the tutu that I had to make), ribbon (anything will work...I actually used the ribbon off of a bouquet of flowers that were brought to the hospital by some friends after I had her) and scissors.
Begin cutting strips in the tulle (you can make the strips as wide as you would like, I did mine approximately 2in. wide). The length of each strip is also up to you. Just keep in mind that the actually length will be the strip folded in half.
After the strips are cut out (you can start with a few and cut them out according to how many you think you will need) begin by tying each strip of tulle onto the ribbon. Tie each piece on in the middle so that you get a double thickness of tulle.
