-Thin Cotton Fabric
-Thread (colour does not matter.)
I bought tulle and a cheap poly-cotton material from my local market as well as an elasticated waistband. To begin with I measured my waist and doubled it by two (round it to the nearest metre or whatever unit of measurement you are using.) I then folded the poly-cotton in half and pinned it to my half way point of my waist band, I then found the 1/4th and 3/4th of the fabric and pinned that to my waistband too.
I then began to fold pleats in between these sections - making sure that all my pleats were in the same direction- until it was all pleated. I then sowed this down and repeated this will the tulle - however I doubled the amount of tulle I used in comparison to the amount of cotton I used to ensure that my petticoat would be larger.
I was originally going to use two petticoats however, I found that it made my skirt look too puffy and I removed one.
This does not mean however that you have to only use one petticoat, if you feel you want to give your dress more poof, feel free to add as many as you like!
Remember to add this to the same waistband so it does not bunch up around your waist and becomes noticeable under your dress.
