I've edited in the two best photos so far, showing the tartan and the left side pleats - you can make out the eleven pleats which make up one half of the sequence.

I will work on the right half and hopefully be able to show the construction in shorter stages.

You do not have to join widths of the fabric, it was just that by doing so I got a better result.

The stripes are closer together the way I have done it, so I get more pleats from the 20 ft of fabric.

Note the stripe going along the edge of the fabric at the waist edge. I cut along a cream stripe to level up the edge of the fabric and create a waist band. I cut off the pieces just above a cream stripe each time, so the stripes would line up along the length. I then sewed along the waist edge aligning the layers by that stripe.
