Divide your waist measurement by 6 and the add 1(x). (Example: for a 30" wasit, divide by 6 and to get 5" add 1 to get 6".) Lay the T-shirt flat and cut a 24"long (slighhtly trapezoidal) strip from each one, using the measurement x for the width of the top of eachstrip. The width of the bottom of each strip should be 1 1/2" wider than the top.
Arrange the strips next to each other in the order you would like them to apper on the skirt and pin them together along the long edges (rights sides together).
Sew along the pinned edges 1/2"from the edges using a running backstitch. Remove the pins and turn the skrit right side out.
