Bum Rolls

I've been reading more about bum rolls, as I really need one to wear with this hoop. I'm used to the side panniers now (they took a while to get used to - my first thought initially was, where on earth do I put my hands?!). I've seen people make a bum roll similar to that made for wearing over a farthingale (see http://www.farthingales.on.ca/bum_roll.html but I'm leaning more towards one that Katherine made recently.
