I love having pretty things made from fabric I love, and my inhaler case is no exception. I really wanted something with stiff sides to protect the inhaler as much as possible, and this case was the result of my testing.
With the method outlined here, you too can make multiple inhaler pouches to suit your needs, and make them as individual as the person carrying them.
The inhaler I made this for measures 9.5cm x 6cm x 4cm. If yours is larger or smaller, then obviously scale the dimensions as required.
