Here we go – let’s turn that meanform to a pattern pieces. I believe the photos tell the whole story, just to remind you  for the allowances you need to use:

folding: 5 mm
trimming: 3 mm
overlap (upper): 6-12 (thinner needs less)
reverse seam: 2-3 mm

And the photos (and this time we can say thanks to my wonderful student, Mary – thanks!)
