First image shows the repair tape used. one side looks slightly reflective as it has hot glue on. The suit material had an ironing symbol of medium heat (two dots), but I found using the iron between medium and hot for 30secs was ok. Its worth practising on other material then on an unseen hem first.

The second image shows some cut up material taken from the hem. The area of material was about 5 times that of the holes. The material was shredded as finely as possible with scissors.
