Hi All! 

I make silk scarves that have a hand rolled hem, and I'm trying to create an actual puckering effect (rather than 'faking' puckering with the puckering tool). 

I know we can increase stich tension if we use sewing....but as this is a single piece of square fabric, I'm not sewing anything together. In real life, I use a pick stich on the rolled hem.

I'm happy with the fake puckering in Clo, it looks convincing, BUT the actual edge of the fabric is too flat. It needs to look more irregular and bumpy as though it has been pick stitched. 

Alternatively - if tension cannot be applied to a top stitch, is it possible to disrupt the edge of fabrics so that they are not straight/flat in Clo?

The work-around, is that I can create a baseline in illustrator with a "wobbly" edge, then import that into Clo as my pattern. This works fine, I just wondered if there is a way to create real/actual puckering tension in Clo as it would kill two birds....I'd get "True" puckering (rather than fake puckering) and I'd also get a nice realistic irregular bumpy tension on the edge of the fabric. 

Pictures below show how the render currently looks. Picture below that is a shot of one of my actual scarf hems to show how the hand roll looks. 

p.s I have not rolled the edges on my Clo model as it cause simulation issues despite having played around lots with fabric thickness and particle distances/quad mesh. I just added a thick render edge.  Perhaps the only way to get what I need, is indeed to roll the edges on the Clo model and sew them/play with tension.....Any ideas welcome. Thanks!
