When you make your own pattern from pants or skirt or short, you will always have the problem of how to curve the waistband.
Last night I had a briljant idea (eventhough I say it myself): What about using a belt. Not a new one, but one used for a couple of months. the belt has the perfect curve for your body.
I tried it with several shorts, and it worked out perfect. you even have the right width :D
I hope you can use this trick :D
