for cub scouts I would recommend you buy a few yards of plaid cloth from your local fabric store (don't worry about what tartan) so that 1 of the boys can volunteer to put on a great kilt. you can walk him through how the stripes in the pattern made it much easier to pleat it evenly with everything spread out on the ground then have him use his scout belt to put it on.
