You can make this great swimmable AND walkable mermaid skirt part of your world by following this simple tutorial.
Step 1: Materials
For this project you will need:
Shiny, stretchy material (it's called "swimmer/dancer fabric)
Coordinating color tulle
Sewing machine/thread and needle (not pictured)
3/8" elastic (not pictured)
Scissors (not pictured)
You can purchase all these items at JoAnn's or any local fabric store.
I made the skirt our of remnants from other projects, but it would cost roughly $30 to make and took about 30 minutes.
The length of the fabric you will need is dependent on your body measurements and width of the fabric so I can't really give any specifics on how much fabric to get. I suggest you wrap the fabric around you to see how much you need to get before purchasing.
Step 2: Prep and sew skirt
Fold your fabric over so it is wide enough for your hips and so the top is at the top of your hips and the bottom is just around your knees.
Lay on the fabric so your hips are at the top.
Use a pen or chalk to outline your body onto the fabric leaving a little bit of a seam allowance. You will need a MUCH bigger seam allowance if you do not get stretch fabric.
Get up carefully to make sure you don't mess up the fold and then pin the fabric along the line you drew.
Cut outside the line and sew the sides together.
I kept the selvage edge on my fabric because I used that as a waistband that I could fold down if I wanted to or wear the skirt in a high-waisted style.
