One of the easiest patterns I know of, that is perfect for beginners, is the Oliver +S Lazy Days skirt.
It’s a free pattern with no seam finishing – which is my least favourite sewing task.
I don’t have many construction photos of this skirt because I made this years ago. This is actually the third kid to wear this skirt. Yay, for hand-me-downs!
