I have a few London jobs coming up so I have been looking at a bag that I can also wheel so I don't have to carry it all the way.  On Saturday I was face painting and my colleague had a really cool rolling holdall from Argos and when looking I found this one http://www.argos.co.uk/webapp/wcs/store ... EN+HOLDALL

Seeing as I usually wear a little miss T-shirt when twisting this will work well.
