Everybody seems to be making reverse Kingussie kilts now - oh well - it just shows that once a good idea gets out there is no holding it back.

Light materials which fray easily could definitely do with a strip of tape added to the hemline.

If it is put on after the pleats are pressed it then it will help to hold them, as it can be made shorter at the folds where it is inside, and longer at folds where it is on the outside.

Before the fabric has time to fray, making a sewing machine done edge of triple zig zag or overlocking, or several rows of simple zig sag if the machine is older/simpler should hold it during the pleating, and then it can be folded up and hidden under the tape, so making it nice and neat.

White tape can be dyed darker with strong tea so it is less noticable.
