I think there are a couple of exceptions to that though; dynamics and cloth can both go a bit weird and janky at very small or very big scales, so sometimes it is best to do simulations at 'default' scale and then bake out and rescale down when done. CBR

You're welcome. You know how you see something somewhere, and you're just hanging around waiting to go to work, and you think, 'oh I'll just have a quick go at that'... and then you see another thing.... no, I love these little micro-modelling challenges - always happy to help with those... Did you get your creases working in the end ?

Hahah thanks @Igor.  You're also a good sport.   Hopefully eventually I'll be on your level when it comes to modelling.  It's hard. :(  Here's a screenshot for the polygon police.
