Made these cotton trousers many, many years ago, I love the batik-y print. I only had a remnant of the fabric, not even enough to make the pockets, I had to use a contrast fabric for those.
So here we are many years later, the trousers are a size too small now, but I still love the fabric.
To expand them, I used an offcut from my stash cut into strips, opened the side seams, and inserted the strips. Replaced the elastic as it was perished after all those years, and hey presto, a now fashionable pair of trousers!
Showing the strips down the sides, they are an equal width, just hanging at an angle!
