I posted previously about how I had made a muslin for the first time. I have now made the actual garment using an Ikat fabric. 
I am really happy with the result but I keep thinking that I would have achieved the same result without having made a muslin!

You are such an experienced and talented sewer, you don’t need a muslin!
You are so good at this that you don’t need a trial run first with a muslin.
