First you need to decide two things:
1. Decide how full and how long you want your tutu. Depending on the size you will need anywhere from 2 yards up to 100 lol
2. Decide if you want the base to be ribbon or elastic.
Now, on we go
You will need to decide how long you want your tutu (when doing this remember that the tulle MUST be folded in half so you end up with a double layer effect and the way we knot them will affect the length if you only cut for a single layer)
~The tulle should be folded in half already, now fold in half again, and again until it looks like this
You should basically have one long skinny piece of tulle.
~Now we cut. You want the pieces to be 3-6 inches long, then just keep going down the long piece until there is no more tulle left to cut
~If you are using ribbon you will need to make two knots (I was able to measure Madison and where the ribbon met, that is where I tied it off. If you do not have a live model you will need their waist measurements. Find the mid point, say their waist is 20 inches, the mid point would be 10 so you would tie the ribbon off at five inches from each side of the mid point.) You do this so the tulle stays in place.
~Starting at one knot we will now tie the pieces on to the ribbon. You are going to do a basic loop knot so you should have one side of the tulle open
And the other side should be connected at the fold
You can either place the tulle on top or under the ribbon, I did this one under
~Place your hand through the loop part of the tulle and grab the remaining tulle and pull through
~Pull to tighten into a knot, but don't pull too hard or you will tear the tulle
~Scrunch the tulle pieces together as tight as you would like, the tighter you scrunch them the fuller the skirt
Just keep tying the tulle on until you reach the other knot. At that point if it is scrunched enough for you then you are done, if not scrunch the pieces together more and keep tying. I like to scrunch them just a little bit, that way as the girl grows the mom can undo on of the ribbon knots and unscrunch the tulle so it can grow with her.
Your finished product should look something like this
You can add to this whatever you want.
If using elastic you will need to make it a few inches smaller than the actual waste size and just sew the ends together then start applying the tulle.
