Now grab your fabric again. From each piece you are going to cut a piece that measures 9" by 14" and a piece that measures 9" by 10". In other words you need two 9x14" pieces and two 9x10" pieces. Before we work with the fabric we will use it to measure out two more pieces of interfacing. The interfacing should be about 1/4" less than the fabric around all sides. You will trim it more towards the end so it doesn't have to be perfect you just need the rough size. You only need one piece of interfacing of each size.
We will work with the 9x14" pieces first. Along the long 14" bottom edge we are going to notch the fabric to allow it to curve.
