Patterning for a maxi skirt

First I had to draw around the front and back of the skirt block. I then needed to extend the length of the skirt, I did this by taking the measurement from my waist to the floor and then extending down.
I then needed to add extra flare to the skirt, I did this by drawing vertical lines coming from the bottom of the darts to the hem. For the front we repeated the same process for the one dart, however to gain the other line I measured from the dart to the centre front and marked off half way, then drew a vertical line down. I then traced the front and back off separartely and then slashed up the vertical line. After that I then closed the darts at the top, this automatically spreads out the bottom of the pattern.
I then re-drew this onto a separate piece of paper to create my final pattern. To my final pattern I added my seam allowance and both the centre front and centre back were to be cut on the fold.
We used a bias grain line to give the skirt more of a flute at the hem, it was also to help the skirt have a much better fit.
Waistband; I had to measure the waist minus the seam allowances, I then added on extra this was to create the overlap where the button hole was to be positioned.
