I recently designed a curved-crease pleated vase with a diagonal shift design element. As far as I can tell, this is a unique design, but I would love to hear if anyone has seen anything like this before. http://rebecca.gieseking.us/2013/09/new-work-copper-diagonal-shift-vase/
The crease pattern for the diagonal shift element is available here: http://rebecca.gieseking.us/2013/09/crease-pattern-diagonal-shift/ Rebecca Gieseking
