Our wheel cover used things like THIS
That's what I have, good piece of kit 🤫
Was the skirt made in Hawaii?I attached two press studs ( stainless steel snap fasteners) to the side of the caravan and three more to a short piece of grass skirt which came with the awning grass skirt but had no provision for it to fit anywhere. The result is the wheel is covered and this short piece attaches to main grass skirt which runs the length of the caravan.Isabella also do one where you fit a short rail above the wheel arch spat and attach the draft skirt to it , looks neat.
