Step 7: Cut your waistband fabric.
Note: I'd recommend using a heavier fabric for the waistband, since you want it to support the weight of the skirt and be sturdy enough that you can put in grommets and laces on the side. For my skirt, I used upholstery-weight velvet.
Lay your pattern out on the fabric, draw along the edges with chalk or washable fabric pen, then cut out the pattern. Make sure to leave a 1" seam allowance on all sides.
Since you need both a front and back side for your waistband, repeat this process to get a second, identical piece. Check the dimensions by holding them up around your waist; ignoring the seam allowance, they should just barely meet at the each side of your hips.
