Back to hippy days. Made my skirt from old shorts I then added 5 inch squares. Cut the shorts below zip in the front and slightly higher on the sides. First row has two extra square. Second row 11/2 to each square on first row and third row is 2 square to each square in 2nd row. The next few rows have 2 extra square per row just gathered in. If you making one chose lighter fabric otherwise your skirt will be very heavy.
