This tutorial is for sewing your own panties, but most especially about using and attaching several types of elastics. Sewing your own panties is fast and easy, really it is much more faster than reading this whole tutorial. You don’t need too much fabric, and can even recycle fabric from old T-shirts. With imaginations, you can have a drawer full of pretty and colorful panties in no time!
