Hi,
I've got a question regarding sewn-in box pleats. My current project is a box-pleated traditional kilt for casual wear. I chose box pleats for better everyday wear, since they tend to hold up better than knife pleats with extended use between washings/pressings. I would also like to sew the pleats in for even better crease retention, but I'm not sure what exactly gets sewn. I want to keep the pleats swinging as naturally as possible while giving the maximum endurance.
The picture below shows the bottom of one of my pleats with the right side unpinned. The pleat is between the black lines. Do I sew top to bottom along every inside edge, where the red circle is; or do I sew top to bottom on every outside edge along the white stripe where the blue circle is?
Or both?



Thanks,
Joshua
