I received a surprise sewing request from my dad. He wanted a replacement curtain for the bathroom in his RV. The old one was falling apart — probably rotten from the sun. The fabric was an upholstery burlap with an interfacing layer for stiffness.
We measured the dimensions (essentially a square with some topstitching) and I duped it using surprisingly well-matched fabric from Austin Creative Reuse . The fabric was only $5.50!
