Handkerchief Skirt w/ Roll Down Waistband from hand-me-down t shirts

Step 10 Making the waistband

-Measure your waist where the top of your pants fit.
-This will be how wide your waistband tube should be
-If you're using an old t-shirt, the tube should be about 8-12inches tall, if not, use a piece of fabric that is
-If you're using new fabric, your piece should be 8-12 inches tall, by your waist long
*note- if you are using a t-shirt, and it's still a tube (folded in half), dived the number in half when you measure it
-Pin and cut
-Sew up where you just cut
