Here’s something slightly more challenging, a flower form. You’ll guess that some twisting is required and the crease that allows this has a defined and easily spotted location point. It’s also locked into shape. Out of interest, this “vital” crease can be altered to provide flowers that are more open.

Once you’ve identified the location for the shorter crease, you can use a template then reduce the length of the book folds to produce a neater CP. My mentor Wayne reckons this will work as a modular with a little tweaking, but I haven’t found a really stable form yet. Either that or I’m just to clumsy to assemble them. My money is on the latter!

Update
The esteemed David Lister writes to BOSmail (in reference to my boat CP) “It is now acceptable to distinguish mountain and valley folds in crease patterns with differently coloured lines such as red and blue. Were your original diagrams coloured?”.

The answer is no, because I thought it simple enough, but perhaps for this flower, it might be a good idea, plus it’s all good practise!

In creating said coloured lines, I realised I’d been over-complicating the design to no good purpose. Originally, a pinch-mark provided the location and the book folds didn’t extend further then was necessary, but in for a pinch, in for a pound. So here’s a revision, almost indistinguishable when folded, but much cleaner crease-wise.
